    aarch64: Fix use of wrong zero enum value
    
    aarch64_get_expected_qualifier was incorrectly comparing an
    aarch64_opnd_qualifier_t against AARCH64_OPND_NIL instead of
    AARCH64_OPND_QLF_NIL (these are the zero values of two different enums).
    A previous patch incorrectly addressed the type mismatch by casting the
    qualifier to (enum aarch64_opnd).
    
    Fix it properly by removing the cast and updating the comparison to use
    AARCH64_OPND_QLF_NIL.
