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.
2) added seperate callback handler for ioctl task managment
(mptctl_taskmgmt_reply), to handle command that timeout
3) rewrite mptctl_bus_reset
4) cleanup ioc_reset callback handlers, introducing wrappers for synronizing
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.
