scsi: elx: efct: Do not hold lock while calling fc_vport_terminate()
Smatch checker reported the following error:
drivers/base/power/sysfs.c:833 dpm_sysfs_remove()
warn: sleeping in atomic context
With a calling sequence of:
efct_lio_npiv_drop_nport() <- disables preempt
-> fc_vport_terminate()
-> device_del()
-> dpm_sysfs_remove()
Issue is efct_lio_npiv_drop_nport() is making the fc_vport_terminate() call
while holding a lock w/ ipl raised.
It is unnecessary to hold the lock over this call, shift where the lock is
taken.
