x86/Intel: don't report multiple errors for a single insn operand

Browse Source 
Multiple errors are more confusing than helpful, as the more generic
one often implies a sufficiently different adjustment than would
actually be needed to fix the code. Additionally it makes it more
cumbersome to add missing error checks, as the testsuite then needs
extra updating.
