Always prefer the operation error when the nw_error is not set (has
value MBIM_NW_ERROR_NONE). If the activation state is ACTIVATED or
ACTIVATING then the behavior doesn't change.
The MBIM command PIN LIST returns only status of pin locks and omits
puk-locked facilities. This caused the pop-up window for unlocking
PUK is not shown after reboot.
Currenty active PUK lock has to be obtained using additional call
for PIN command but only single facility is supported this way.
On MBIM modems the type of PIN cannot be specified in MBIM_CID_PIN query
command and the modem responds only remaining attempts for the currently
active lock.
If PIN1 is unlocked and user tries to disable (or enable) it, MM won't
get an update of remaining attempts in response to PIN Query. This value
is returned only after the Set command and MM need to store it in
all (pin/puk)_set_(enter/enable/change)_ready functions.
Previous solution was to call the mm_iface_modem_update_unlock_retries
directly from these functions but it caused the notification to be send
too early and invalid number was displayed to user sometimes.
Instead of this MM will store numbers of remaining attempts and send
them in a single notification from modem_load_unlock_retries.
According to MBIM specification, the subscriber state is INITIALIZED
when SIM card is incompatible with enabled modem personalization lock.
This patch introduce additional check for enabled PIN lock in such case
and fixes depersonalization of one lock if several are enabled.
Calling the mm_iface_modem_update_unlock_retries function directly from
pin_set_enter_ready caused a notification to be send too early with
invalid number of attempts to unlock on MBIM modems.
The mm_iface_modem_update_unlock_retries is already called for all
modems from send_pin_ready (mm-base-sim.c).
