[Libguestfs] [PATCH] inspect: Don't free uninitialized string.

[Richard W.M. Jones]

libguestfs: trace: v2v: read_lines "/etc/os-release"
[...]
libguestfs: trace: v2v: read_lines = ["NAME=Fedora", "VERSION="20 (Heisenbug)"", "ID=fedora", "VERSION_ID=20", "PRETTY_NAME="Fedora 20 (Heisenbug)"", "ANSI_COLOR="0;34"", "CPE_NAME="cpe:/o:fedoraproject:fedora:20"", "HOME_URL="https://fedoraproject.org/"", "BUG_REPORT_URL="https://bugzilla.redhat.com/"", "REDHAT_BUGZILLA_PRODUCT="Fedora"", "REDHAT_BUGZILLA_PRODUCT_VERSION=20", "REDHAT_SUPPORT_PRODUCT="Fedora"", "REDHAT_SUPPORT_PRODUCT_VERSION=20"]

At this point libguestfs segfaulted.

It seems as if 'major' is not used here, so don't try to free it.

This fixes commit 32d19e3289bc259901f77398703f16cf6eabd510.
