Revert "xattr: switch to CLASS(fd)"
This reverts commit 5a1e865e51063d6c56f673ec8ad4b6604321b455 which is
commit a71874379ec8c6e788a61d71b3ad014a8d9a5c08 upstream.
A backporting mistake erroneously removed file descriptor checks for
`fgetxattr`, `flistxattr`, `fremovexattr`, and `fsetxattr` which lead to
kernel panics when those functions were called from userspace with a
file descriptor which did not reference an open file.
