generic: ar8216: introduce ar8216_mib_op helper
The ar8216_mib_{capture,flush} functions are similar. Move the common code into a helper and use that from the original functions. This change also fixes a lockdep warning in ar8216_mib_flush. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> SVN-Revision: 34297
