[PATCH 1/2] riscv: Fix early alternative patching

[Samuel Holland]

Now that the text to patch is located using a relative offset from the
alternative entry, the text address should be computed without applying
the kernel mapping offset, both before and after VM setup.

Fixes: 8d23e94a4433 ("riscv: switch to relative alternative entries")
