sys/vfs/msdosfs: Fix a serious off by 1 for cluster bitmap
from freebsd/freebsd@4159786890522d187529c336eb6da4029f04a3e1
Fixed a serious off by 1 error. The cluster-in-use bitmap was overrun
by 1 u_int if the number of clusters was 1 more than a multiple of
(8 * sizeof(u_int)). The bitmap is malloced and large (often huge), so
fatal overrun probably only occurred if the number of clusters was 1
more than 1 multiple of PAGE_SIZE/8.
