Max Filippov 2201f31f2c xtensa: use actual syscall number in do_syscall_trace_leave ...

Syscall may alter pt_regs structure passed to it, resulting in a
mismatch between syscall entry end syscall exit entries in the ftrace.
Temporary restore syscall field of the pt_regs for the duration of
do_syscall_trace_leave.
