libglusterfsclient: Clean up fini and umount code paths
This patch cleans up the umount and fini paths in preparation to support waiting for unwind of all pending call frames. Two misc fixes are: 1. Fix to avoid deadlock in _libgf_umount by using _libgf_vmp_search_entry instead of libgf_vmp_search_exact_entry since the latter tries to take a lock already help by _libgf_umount. 2. Avoid a crash in _libgf_umount by deleting the vmp entry from the list before it gets freed. Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 279 (File written with booster results in self-heal after dd exits) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=279
