[GlobalISel] Fix an assertion failure in matchHoistLogicOpWithSameOpcodeHands().

We use this combine in the AArch64 postlegalizer combiner, which causes this
function to query the legalizer rules for the action for an invalid opcode/type
combination (G_AND and p0). Moving the legalizer query until after the validity
check in matchHoistLogicOpWithSameOpcodeHands() fixes this.
