ocs_fc: IO timeout handling and error reporting fix.

Hardware timeout uses a 8-bit timeout value and expects the timeout to
be less than 255 seconds. Added software timer implemetation to timeout
and abort the IOs with timeout more than 255 seconds.

Fix the timeout problem by dividing CAM timeouts by 1000 as hardware
expects timeout value in seconds.  Before this change, CAM timeouts in
milliseconds were getting truncated to 8 bits and converted to seconds.
So the actual timeout used when going down to the card would depend on
the bottom 8 bits of the timeout used.

Add the mapping of ocs_fc error status to CAM status.
