[PATCH v4 2/3] fs: make file_listxattr and file_removexattr helpers non-static

In preparation for adding IORING_OP_FREMOVEXATTR and
IORING_OP_FLISTXATTR support in io_uring, we need to invoke the VFS-layer
helpers from within io_uring.

Make the following helpers non-static and declare them in fs/internal.h:
- file_listxattr()
- file_removexattr()

No functional change is introduced.
