common: set _fs_has_crcs=0 as default in _filter_mkfs()
xfsprogs without crc support won't print crc=0/crc=1, so
_filter_mkfs() leaves _fs_has_crcs variable unset, and xfs/033 fails
because of that.

Print _fs_has_crcs=0 to stderr by default, so old xfsprogs could have
this variable set too, and a latter _fs_has_crcs=1 could overwrite it
if the fs does have crc support.
