[PATCH] lpfc 8.1.3: Fix deadlock in lpfc_fdmi_tmo_handler
Fix deadlock in lpfc_fdmi_tmo_handler
lpfc_fdmi_tmo_handler was calling lpfc_fdmi_cmd with the host_lock
held. lpfc_fdmi_cmd assumes the host_lock is released as it calls functions
that acquire the host_lock. lpfc_fdmi_tmo_handler acquired the host_lock to
protect access to work_hba_events. This was already checked in the worker
thread so we can remove that code completely and remove access to the
host_lock.
