Subject: [PATCH] [GFS2] Fix a bug on i386 due to evaluation order

Since gcc didn't evaluate the last two terms of the expression in
glock.c:1881 as a constant expression, it resulted in an error on
i386 due to the lack of a 64bit divide instruction. This adds some
brackets to fix the problem.

This was reported by Andrew Morton.
