Elvira Khabirova 6c96c0b2e3 mips: fix syscall_get_nr 
commit 85cc91e2ba upstream.

The implementation of syscall_get_nr on mips used to ignore the task
argument and return the syscall number of the calling thread instead of
the target thread.

The bug was exposed to user space by commit 201766a20e ("ptrace: add
PTRACE_GET_SYSCALL_INFO request") and detected by strace test suite.

Fixes: c2d9f17757 ("MIPS: Fix syscall_get_nr for the syscall exit tracing.")
