riscv: Preserve savectx return address with vector supportHEADmain

Calling vector_state_store_savectx() overwrites ra with the address of
the following ret instruction.  The ret consequently branches to itself
and prevents kernel dumps from progressing past dump_savectx().

Tail-call vector_state_store_savectx() so that it returns directly to
the original savectx() caller.
