Laurent Pinchart 6d00f4ec12 media: uvcvideo: Fix menu count handling for userspace XU mappings
When commit 716c330433e3 ("media: uvcvideo: Use standard names for
menus") reworked the handling of menu controls, it inadvertently
replaced a GENMASK(n - 1, 0) with a BIT_MASK(n). The latter isn't
equivalent to the former, which broke adding XU mappings from userspace.
Fix it.
