IB/srp: Don't schedule reconnect from srp
If there is a problem in the connection, the SCSI mid-layer will eventually call srp_reset_host(), which will call srp_reconnect(), so we do not need to schedule a call to srp_reconnect_work() from srp_completion(). Removing this prevents srp_reset_host() from failing if a reconnect scheduled from srp_completion() is already in progress, which in turn was causing crashes as both SCSI midlayer and srp_reconnect() were cancelling commands.
