arm64: signal: Make force_signal_inject more robust
force_signal_inject is a little flakey:
* It only knows about SIGILL and SIGSEGV, so can potentially deliver
other signals based on a partially initialised siginfo_t
* It sets si_addr to point at the PC for SIGSEGV
* It always operates on current, so doesn't need the regs argument
This patch fixes these issues by always assigning the si_addr field to
the address parameter of the function and updates the callers (including
those that indirectly call via arm64_notify_segfault) accordingly.
