signal/xtensa: Consistenly use SIGBUS in do_unaligned_user
While working on changing this code to use force_sig_fault I discovered that do_unaliged_user is sets si_signo to SIGBUS and passes SIGSEGV to force_sig_info. Which is just b0rked. The code is reporting a SIGBUS error so replace the SIGSEGV with SIGBUS.
