Ville Juven 10e44f8915 riscv_fork.c: Fix race condition when handling parent integer registers 
We need to record the parent's integer register context upon exception
entry to a separate non-volatile area. Why?

Because xcp.regs can move due to a context switch within the fork() system
call, be it either via interrupt or a synchronization point.

Fix this by adding a "sregs" area where the saved user context is placed.
The critical section within fork() is also unnecessary.
