Jiaxun Yang 78f459dce4 MIPS: scall: Save thread_info.syscall unconditionally on entry 
[ Upstream commit 4370b673ccf240bf7587b0cb8e6726a5ccaf1f17 ]

thread_info.syscall is used by syscall_get_nr to supply syscall nr
over a thread stack frame.

Previously, thread_info.syscall is only saved at syscall_trace_enter
when syscall tracing is enabled. However rest of the kernel code do
expect syscall_get_nr to be available without syscall tracing. The
previous design breaks collect_syscall.

Move saving process to syscall entry to fix it.
