[SCSI] mpt fusion: rewrite taskmgmt request and completion routines
1.) rewrite taskmanagement request and completion routines, making them single threaded and using the generic MPT_MGMT struct, deleting mptscsih_TMHandler, replacing with single request TM handler mptscsih_IssueTaskMgmt, and killing the watchdog timer functions. 2.) cleanup ioc_reset callback handlers, introducing wrappers for synchronizing error recovery (mpt_set_taskmgmt_in_progress_flag, mpt_clear_taskmgmt_in_progress_flag), as the fusion firmware only handles one task management request at a time Signed-off-by: Kashyap Desai <kadesai@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
