mptfusion: delete watchdogs timers from mptctl and mptscsih 

From: 	Moore, Eric Dean <Eric.Moore@lsil.com>

1) mptscsih.c: I have changed task management 
requests so they complete in same thread before returning
to os.  I removed the TMtimer code.  
 
(2) mptctl.c: I have deleted both TMtimer and timer code. Replaced
with wait_event_interruptible_timeout.  So commands are now
completed in same thread.  
 
(3) mptctl_do_fw_download - nasty polling of global parameters
that are set in contents of interrupt handler(mptctl_reply), now using
wait_event_interruptible_timeout. 
 
(4) I have cleaned up mptctl_reply.
