signal/x86: Call force_sig_pkuerr from __bad_area_nosemaphore
There is only one code path that can generate a pkuerr signal. That
code path calls __bad_area_nosemaphore and can be dectected by testing
if si_code == SEGV_PKUERR. It can be seen from inspection that all of
the other tests in fill_sig_info_pkey are unnecessary.
Therefore call force_sig_pkuerr directly from __bad_area_semaphore and
remove fill_sig_info_pkey.
At the same time move the comment above force_sig_info_pkey into
bad_area_access_error, so that the documentation about pkey generation
races is not lost.
