MIPS16/GAS: Streamline forced size suffix handling code

Clean up after commit 112cf77b1855 ("MIPS: use is_whitespace()") and
untangle the code flow in the handling of forced size suffixes, noting
that owing to the loop right above the only data `c' can hold at this
point is '\0', '.', or a white-space character.  No functional change.
