tc: pedit: Fix parse_cmd()
This was horribly broken:
* pack_key8() and pack_key16() ...
* missed to invert retain value when applying it to the mask,
* did not sanitize val by ANDing it with retain,
* and ignored the mask which is necessary for 'invert' command.
* pack_key16() did not convert mask to network byte order.
* Changing the retain value for 'invert' or 'retain' operation seems
just plain wrong.
* While here, also got rid of unnecessary offset sanitization in
pack_key32().
* Simplify code a bit by always assigning the local mask variable to
tkey->mask before calling any of the pack_key*() variants.
