MIPS: restore INLINE_SYSCALL macro

The MIPS specific INLINE_SYSCALL macro has been renamed to
INLINE_SYSCALL_NCS with:

  763bbf9e9a27426c9be8322dca5ddf2cb4dbc464

  syscall: unify part 2: NCS variety

  Declare common NCS (non-constant syscall) variants and convert the
  existing ports over to this.

This change breaks system calls. The code generated with using of the
new macro does not obey the restartable syscall convention used by the
linux kernel. When it tries to restart the syscall the errno value is
not being replaced by the syscall number.

This causes weird behaviour of the 'ping' command in busybox for
example:

root@OpenWrt:/# ping 192.168.1.254
