ethernet: sun: add check for the mdesc_grab()

Browse source

[ Upstream commit 90de546d9a ]

In vnet_port_probe() and vsw_port_probe(), we should
check the return value of mdesc_grab() as it may
return NULL which can caused NPD bugs.

Fixes: 5d01fa0c6b ("ldmvsw: Add ldmvsw.c driver code")
Fixes: 43fdf27470 ("[SPARC64]: Abstract out mdesc accesses for better MD update handling.")
