quota: Fix dquot_transfer for filesystems different from ext4
Commit fd8fbfc1 modified the way we find amount of reserved space belonging to an inode. The amount of reserved space is checked from dquot_transfer and thus inode_reserved_space gets called even for filesystems that don't provide get_reserved_space callback which results in a BUG. Fix the problem by checking get_reserved_space callback and return 0 if the filesystem does not provide it. CC: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: Jan Kara <jack@suse.cz>
