RISC-V: simplify register width check in ISA string parsing

Saving off the `isa` pointer to a temp variable, followed by checking if
it has been incremented is a bit of an odd pattern. Perhaps it was done
to avoid a funky looking if statement mixed with the ifdeffery.

Now that we use IS_ENABLED() here just return from the parser as soon as
we detect a mismatch between the string and the currently running
kernel.
