[PATCH for-5.0 06/31] block: Keep BDRV_O_NO_IO in *inherited_fmt_options

[Max Reitz]

bdrv_inherited_fmt_options() is used only by (pseudo-)filter drivers,
namely quorum and blkverify.  Both should pass on BDRV_O_NO_IO to their
children.  There is no reason to clear it in
bdrv_inherited_fmt_options().
