Fix snapshot automounting with GrSecurity constify plugin.
./configure erroneously detects absence of dops->d_automount
when built against a GrSecurity patched kernel.
Summerized error message found in config.log:
checking whether dops->d_automount() exists
...
In function 'main': ... error: constified variable 'dops'
cannot be local
The "dops" variable cannot be a local variable, so it's
moved to the global scope.
This test also fails if the prototype of the dops->d_automount
function pointer is changed.
