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.
