I added slightly modified version to the master branch
(there was a code shuffle so the function is moved to libcryptsetup internally).

Anyway, I added handling of -EINTR for read() and code will retry instead
of failing in this case - we have already wrapper read_buffer for that.

I will probably backport this later for stable 1.7.6.

Thanks,
Milan
