linux-user: do_setsockopt: make ip_mreq local to the place it is used and inline target_to_host_ip_mreq()

ip_mreq is declared at the beginning of do_setsockopt(), while
it is used in only one place.  Move its declaration to that very
place and replace pointer to alloca()-allocated memory with the
structure itself.

target_to_host_ip_mreq() is used only once, inline it.

This change also properly handles TARGET_EFAULT when the address
is wrong.
