xfs: Fix uninitialized variable in xfs_reflink_reserve_cow_range()
with gcc 4.1.2: fs/xfs/xfs_reflink.c: In function xfs_reflink_reserve_cow_range: fs/xfs/xfs_reflink.c:327: warning: error may be used uninitialized in this function Indeed, if "count" is zero, the function will return an uninitialized error value. While "count" is unlikely to be zero, this function is called through the public iomap API. Hence fix this by preinitializing error to zero.
