[SCSI] mpt fusion: rewrite of ioctl_cmds internal generated function
1) rewrite of ioctl_cmds internal generated function that issue commands to firmware, porting them to be single threaded using the generic MPT_MGMT struct. All wait Queues are replace by completion Queue. 2) added seperate callback handler for ioctl task managment (mptctl_taskmgmt_reply), to handle command that timeout 3) rewrite mptctl_bus_reset Signed-off-by: Kashyap Desai <kadesai@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
