1) s/mi/mfi/ in FreeBSD ioctl path
2) add in "\n" on various failure messages
3) cap the length of time to abort an AEN command
4) fix passing sense data back to user to make Dell's Linux firmware
upgrade tool happy.
5) bump the MFI_POLL_TIMEOUT_SECS from 10s to 50s since the
firmware flash command can take ~40s to return.
This is some clean-up and enables RAID firmware to updated via Dell's
tool. Note Dell's tool requires the updates to the Linux emulator
that has been done in -current with TLS etc.
I need to discuss with scottl how to better submit mfi commands to
the firmware via the ioctl path so we don't do it in polled mode.
