Delete an error message for a failed memory allocation
Return directly after a failed kzalloc()

This issue was detected by using the Coccinelle software.

* Return directly after a call of the function "kzalloc" failed

* Delete an initialisation and a check (for the local variable "kms")
which became unnecessary with this refactoring.
