PPC: fix segfault in signal handling code
Removed h2g() macro around the ka->_sa_handler due to the _sa_handler being a
guest memory address.
Changed the __put_user to put_user as it was attempting to put a value at the
stack address but the new address is a guest memory address, __put_user is
for host memory addresses.
