metag/usercopy: Add missing fixups
[ Upstream commit b884a190afcecdbef34ca508ea5ee88bb7c77861 ]
The rapf copy loops in the Meta usercopy code is missing some extable
entries for HTP cores with unaligned access checking enabled, where
faults occur on the instruction immediately after the faulting access.
Add the fixup labels and extable entries for these cases so that corner
case user copy failures don't cause kernel crashes.
