commit 4cb3fde7c9224ca4f939852c5e7987fc5112d680

learn: Check learn actions after parsing in learn_parse().
		
learn_parse() and learn_check() are supposed to apply the same checks, but
they are implemented very differently.  It seems best to have learn_parse()
actually call learn_check() just to be sure.

This would have caught the bug fixed in the previous commit, because
the tests actually contain instances of "learn" actions that trigger the
bug, but the tests only parsed the actions without ever doing anything
that checked them (like sending them to ovs-vswitchd over OpenFlow).

learn: Allow read-only fields to be matched.
		
nxm_dst_check() requires a writable field.  Since NX_LEARN_DST_MATCH only
matches on a field and doesn't write to a field, use nxm_src_check() for
that case instead.

Bug #7507.
