nx-match: New helpers.
This patch creates two new helper functions, nxm_reg_load() and
nxm_dst_check(). The new nxm_dst_check() function may be used to
check the validity of destination fields used by actions. The new
nxm_reg_load() function may be used by actions which need to write
to NXM fields.
This patch also allows multipath and autopath to write their result
to non-register NXM fields.
