vfs_gpfs: add sys_proc_fd_path() fallback to vfs_gpfs_fset_dos_attributes()
gpfs_set_winattrs() is a modifying operation, my expectation thus is that it is
not allowed on pathref (O_PATH) handles even though a recent Linux kernel commit
44a3b87444058b2cb055092cdebc63858707bf66 allowed calling utimensat() on pathref
handles.

RN: Some VFS operations on pathref (O_PATH) handles fail on GPFS
