[SCSI] lpfc 8.1.10 : Add support for dev_loss_tmo_callbk and fast_io_fail_tmo_callbk
Add support for new dev_loss_tmo callback Goodness is that it removes code for a parallel nodev timer that existed in the driver Add support for the new fast_io_fail callback Signed-off-by: James Smart <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
