[PATCH 03/14] PMFS: Remove use of unreasonably large constant

[Matthew Wilcox]

From: Matthew Wilcox <willy at linux.intel.com>

Sparse warned:
fs/pmfs/bbuild.c:71:31: warning: constant 0xFFFFFFFFFFFFFF00 is so big it is unsigned long

The code is actually trying to determine whether the bottom 8 bits are
all clear, which we already calculated on the previous line.  So just
test that instead.
