IB/srp: Remove target from list before freeing Scsi_Host structure
Remove an SRP target from the SRP target list before invoking the last
scsi_host_put() call. This change is necessary because that last put
frees the memory that holds the srp_target_port structure.
This patch prevents the following kernel oops:
RIP: 0010:[<ffffffff810b00d0>] __lock_acquire+0x500/0x1570
