mips: fix compat_sys_lseek syscall
This is almost compatible, but passing a negative offset should result in a EINVAL error, but on mips o32 compat mode would seek to a large 32-bit byte offset. Use compat_sys_lseek() to correctly sign-extend the argument. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
