Charlie Jenkins 5b3d6103b3 riscv: entry: Split ret_from_fork() into user and kernel ...

This function was unified into a single function in commit ab9164dae2
("riscv: entry: Consolidate ret_from_kernel_thread into ret_from_fork").
However that imposed a performance degradation.

Partially reverting this commit to have ret_from_fork() split again,
results in a 1% increase on the number of times fork is able to be called
per second.
