misc: ibmvsm: Fix potential NULL pointer dereference
There is a potential NULL pointer dereference in case kzalloc()
fails and returns NULL.
Fix this by adding a NULL check on *session*
Also, update the function header with information about the
expected return on failure and remove unnecessary variable rc.
This issue was detected with the help of Coccinelle.
Fixes: 0eca353e7ae7 ("misc: IBM Virtual Management Channel Driver (VMC)")
