devtmpfs: drop redundant fs parameters from internal fs

The internal_fs_type is mounted via vfs_kernel_mount() and is never
registered as a filesystem, thus specifying the parameters is redundant
as those params will not be validated by fs_validate_description().

Both {shmem,ramfs}_fs_parameters are anyway validated when those
respective filesystems are first registered, so there is no reason to
pass them to devtmpfs too, drop them.
