KVM: emulate: do not adjust size of fastop and setcc subroutines
commit 79629181607e801c0b41b8790ac4ee2eb5d7bc3e upstream.
Instead of doing complicated calculations to find the size of the subroutines
(which are even more complicated because they need to be stringified into
an asm statement), just hardcode to 16.
It is less dense for a few combinations of IBT/SLS/retbleed, but it has
the advantage of being really simple.
