protocol: remove the option 'verify-volfile-checksum'

'getspec' operation is not used between 'client' and 'server' ever since
we have off-loaded volfile management to glusterd, ie, at least 7 years.

No reason to keep the dead code! The removed option had no meaning,
as glusterd didn't provide a way to set (or unset) this option. So,
no regression should be observed from any of the existing glusterfs
deployment, supported or unsupported.

Updates: CVE-2018-14653

Updates: bz#1644756
