size= is specified in bits, but arg_key_size stores bytes after
parsing. The parser used arg_key_size as temporary storage before
validation. When the value was not divisible by 8, the warning said
the option was ignored, but the invalid bit count remained.
Parse into a local variable and update arg_key_size only after
validation.
Repro:
build/systemd-cryptsetup attach sdscan /tmp/plain.img /tmp/key \
plain,size=7
Before: warned ignored, then used key size 56 bits.
After: warned ignored, then kept the default key size 256 bits.
