signal/xtensa: Consistenly use SIGBUS in do_unaligned_user

commit 7de712ccc096b81d23cc0a941cd9b8cb3956605d upstream.

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.
