btrfs: Fix build error while LIBCRC32C is module
If CONFIG_BTRFS_FS is y and CONFIG_LIBCRC32C is m, building fails: fs/btrfs/super.o: In function `btrfs_mount_root': super.c:(.text+0xb7f9): undefined reference to `crc32c_impl' fs/btrfs/super.o: In function `init_btrfs_fs': super.c:(.init.text+0x3465): undefined reference to `crc32c_impl' fs/btrfs/extent-tree.o: In function `hash_extent_data_ref': extent-tree.c:(.text+0xe60): undefined reference to `crc32c' extent-tree.c:(.text+0xe78): undefined reference to `crc32c' extent-tree.c:(.text+0xe8b): undefined reference to `crc32c' fs/btrfs/dir-item.o: In function `btrfs_insert_xattr_item': dir-item.c:(.text+0x291): undefined reference to `crc32c' fs/btrfs/dir-item.o: In function `btrfs_insert_dir_item': dir-item.c:(.text+0x429): undefined reference to `crc32c' Select LIBCRC32C to fix it.
