[PULL 06/35] linux-user: do_setsockopt: eliminate goto in switch for SO_SNDTIMEO

[Richard Henderson]

From: Michael Tokarev <m...@tls.msk.ru>

There's identical code for SO_SNDTIMEO and SO_RCVTIMEO, currently
implemented using an ugly goto into another switch case.  Eliminate
that using arithmetic if, making code flow more natural.
