drivers: base: swnode: check if swnode is NULL before dereferencing it
The to_software_mode() macro can potentially return NULL, so also add
a NULL check on swnode before dereferencing it to avoid any NULL
pointer dereferences.
Detected by CoverityScan, CID#1476052 ("Explicit null dereferenced")
Fixes: 59abd83672f7 (drivers: base: Introducing software nodes to the firmware node framework)
