commit 845c87b67b7bfd60127e23d1df93a94ceb9d3d18
Author: NeilBrown <neilb@suse.com>

mount: Fix problems with parsing minorversion=
1/ minorversion=0 is not recognized, as errors from
strtol() are not correctly detected.
2/ when there is an error in the minorversion= value,
no message is presented.
3/ Current code recognizes "minorversion" and sets V_SPECIFIC,
but then because *cptr == '\0', the v_mode is reset to V_GENERAL.
This results in minorversion negotiation, which is not wanted.
This patch addresses all of these.
