If export mount flag is not passed in, set default parameters
for export structure and pass that to vfs_export().
Currently in userland mount(8), an export structure is unconditionally
passed in, only for UFS. This is an attempt to move that UFS-specific
behavior out of mount(8) and into the UFS filesystem code.
