Al Viro 1e66a472b5 m68k: Handle arrivals of multiple signals correctly

[ Upstream commit 4bb0bd81ce5e97092dfda6a106d414b703ec0ee8 ]

When we have several pending signals, have entered with the kernel
with large exception frame *and* have already built at least one
sigframe, regs->stkadj is going to be non-zero and regs->format/sr/pc
are going to be junk - the real values are in shifted exception stack
frame we'd built when putting together the first sigframe.

If that happens, subsequent sigframes are going to be garbage.
Not hard to fix - just need to find the "adjusted" frame first
and look for format/vector/sr/pc in it.
