small followup to recent Xtensa patch

[Bob Wilson]

Fix a minor glitch in one of my recent changes: if the section alignment
is smaller than the size of a branch target instruction, the assembler
was failing.  Committed on the mainline and 2.16 branches.

        * config/tc-xtensa.c (get_aligned_diff): Handle target_size
larger
        than the section alignment.
