[PATCH 2/2] wifi: rtw88: ps: Trigger firmware recovery when failing to leave LPS state

[Kalpesh Solanki]

When rtw_fw_leave_lps_check() fails, the firmware has locked up or
failed to exit its low power state. Currently, the driver only logs
'firmware failed to leave lps state' and clears REG_TCR, leaving the
hardware in an unresponsive state where subsequent H2C commands fail
and TX traffic hangs indefinitely.

Call rtw_fw_recovery() when rtw_fw_leave_lps_check() fails so the driver
can automatically reset the hardware and re-sync without requiring manual
user intervention.
