pgsql: pgindent run on access/transam/multixact.c

pgindent run on access/transam/multixact.c

This file has been patched over and over, and the differences to master
caused by pgindent are annoying enough that it seems saner to make the
older branches look the same.

Backpatch to 9.3, which is as far back as backpatching of bugfixes is
necessary.

Branch
------
REL9_4_STABLE
