On ARM64, when the BPF JIT compiler fills the JIT image body with
opcodes during translation of eBPF into ARM64 opcodes, we may fail
for several reasons during that phase: one being that we jump to
the notyet label for not yet supported eBPF instructions such as
BPF_ST. In that case we only free offsets, but not the actual
allocated target image where opcodes are being stored. Fix it by
calling module_free() on dismantle time in case of errors.
