[IA64] Fix __{in,out}s{w,l} to handle unaligned data
Some ia64 systems produce several repeats of kernel messages like this:
kernel unaligned access to 0xe000000644220466, ip=0xa000000100516fa1
This was tracked to ide code using the __cmd[] field in "struct request"
via the __outsw() function. __cmd[] is a char array, so is not guaranteed
to be properly aligned when accessed as words.
