[PATCH 18/23] aarch64: Add QLF_ERR to aarch64_opnd_qualifiers
This patch adds an entry for AARCH64_OPND_QLF_ERR to the aarch64_opnd_qualifiers array. Although this entry should ideally never be used, its presence ensures that the array length matches the enum length, improving code robustness and preventing potential out-of-bounds memory accesses, though such accesses would have been detected previously.
