WANG Xuerui b3be12767c mips: Fix argument passing for inlined syscalls on Linux [BZ #25523]
According to [gcc documentation][1], temporary variables must be used for
the desired content to not be call-clobbered.

Fix the Linux inline syscall templates by adding temporary variables,
much like what x86 did before
(commit 381a0c26d7).

Tested with gcc 9.2.0, both cross-compiled and natively on Loongson
3A4000.
