smb/server: map SET_INFO ENOSPC to disk full

FILE_ALLOCATION_INFORMATION can call vfs_fallocate(). If the allocation
cannot be satisfied, vfs_fallocate() returns -ENOSPC.

smb2_set_info() did not map -ENOSPC, so ksmbd returned a generic SMB error
and the client reported EIO instead of ENOSPC. This makes the ENOSPC step
in xfstests generic/213 fail.

Map -ENOSPC and -EFBIG to STATUS_DISK_FULL in the SET_INFO error path.

Tested with xfstests generic/213 on ksmbd.
