net/compat: fix dev_ifsioc emulation corner cases
Handling for SIOCSHWTSTAMP is broken on architectures with a split user/kernel address space like s390, because it passes a real user pointer while using set_fs(KERNEL_DS). A similar problem might arise the next time somebody adds code to dev_ifsioc. Split up dev_ifsioc into three separate functions for SIOCSHWTSTAMP, SIOC*IFMAP and all other numbers so we can get rid of set_fs in all potentially affected cases.
