KVM: Standardize on "int" return types instead of "long" in kvm_main.c
KVM functions use "long" return values for functions that are wired up
to "struct file_operations", but otherwise use "int" return values for
functions that can return 0/-errno in order to avoid unintentional
divergences between 32-bit and 64-bit kernels.
Some code still uses "long" in unnecessary spots, though, which can
cause a little bit of confusion and unnecessary size casts. Let's
change these spots to use "int" types, too.
