KVM: S390: fix potential array overrun in intercept handling
commit 062d5e9b0d714f449b261bb522eadaaf6f00f438 upstream.
kvm_handle_sie_intercept uses a jump table to get the intercept handler
for a SIE intercept. Static code analysis revealed a potential problem:
the intercept_funcs jump table was defined to contain (0x48 >> 2) entries,
but we only checked for code > 0x48 which would cause an off-by-one
array overflow if code == 0x48.
Use the compiler and ARRAY_SIZE to automatically set the limits.
