deny partial write for loop dev fd
Partial write can be easily supported by LO_CRYPT_NONE mode, but it is not
easy in LO_CRYPT_CRYPTOAPI case, because of its block nature. I don't know
who still used cryptoapi, but theoretically it is possible. So let's leave
things as they are. Loop device doesn't support partial write before
Nick's "write_begin/write_end" patch set, and let's it behave the same way
after.
