[ Upstream commit 1c3ace2b8b ]
Although harmless, the return statement in kvm_unexpected_el2_exception
is rather confusing as the function itself has a void return type. The
C standard is also pretty clear that "A return statement with an
expression shall not appear in a function whose return type is void".
Given that this return statement does not seem to add any actual value,
let's not pointlessly violate the standard.
Build-tested with GCC 10 and CLANG 13 for good measure, the disassembled
code is identical with or without the return statement.
