[PATCH] VFAT: ->i_[cam]time cleanups (1/6)

From René Scharfe <l.s.r@web.de>

there's one call to strncpy() in vfat that really should be a memcpy().
The source, msdos_name, is a space-filled char array, not a
NUL-terminated string.

The rest of the patch eliminates duplicate occurencies of the
CURRENT_TIME macro inside functions. This shrinks vfat.o by a few
bytes.
