[PATCH 02/23] aarch64: Fix use of wrong zero enum value

[Alice Carlotti]

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.
