For mount, discover f_mntonname from supplied path argument
using vn_fullpath_global(). This fixes f_mntonname if mounting
inside chroot, jail or with relative path as argument.

For unmount in jail, use vn_fullpath_global() to discover
global path from supplied path argument. This fixes unmount in jail.
