block: sunvdc: add check for mdesc_grab() returning NULL
[ Upstream commit 6030363199e3a6341afb467ddddbed56640cbf6a ]
In vdc_port_probe(), we should check the return value of mdesc_grab() as
it may return NULL, which can cause potential NPD bug.
Fixes: 43fdf27470b2 ("[SPARC64]: Abstract out mdesc accesses for better MD update handling.")
