When lpfc generates a GEN_REQUEST wqe for the nvme LS (such as Create
Association), the timeout is set to R_A_TOV  without regard to the
timeout value supplied by the nvme-fc transport. The driver should be
setting the timeout to the value passed into the routine. Additionally
the caller should be setting the timeout value to the value in the ls
request set by the nvme transport. Instead, it unconditionally is
setting it to a driver defined value.  So the driver actually overrode
the value twice.

Fix by using the timeout provided to the routine, and for the caller,
set the timeout to the ls request timeout value.
