drivers: base: swnode: check if pointer p is NULL before dereferencing it
The pointer p can be potentially NULL as macro to_software_node can
return NULL.
Add null check on p before dereferencing it to avoid any NULL pointer
dereferences.
Detected by CoverityScan, CID#1476039 ("Explicit null dereferenced")
Fixes: 59abd83672f7 (drivers: base: Introducing software nodes to the firmware node framework)
