Use %zu format instead of %lu to print variable of size_t type.
This fixes the following gcc build error on 32-bit targets:
error: format '%lu' expects argument of type 'long unsigned int',
but argument 3 has type 'size_t' {aka 'unsigned int'}
Fixes: 71ebe3842ebe ("nvmet-auth: Diffie-Hellman key exchange support")
