libglusterfsclient: traverse the vmplist during fini only if any entries are mounted.
- the vmplist.list is inited only during mounting of first entry. Hence doing
a list traversal when no vmpentries are present, results in a segfault.
Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
BUG: 282 (segfault of applications using booster observed when the application does not mount any vmps.)
