cf57298af5336df2aece47ef16c290a3a81457dd qemu-io: better input validation for vector-based commands
Fix up a couple of issues with validating the input of the various
length arguments for the vectored I/O commands:
- do the alignment check on each length instead the always 0 count argument
- use a long long varibale for the cvtnum return value so that we can check
wether it wasn't a number
- check for a too large argument instead of truncating it
Also refactor it into a common helper for all four calers and avoid parsing
the numbers twice.
