The kfree() function was called in one case by
the fcoe_sysfs_fcf_add() function during error handling
even if the passed variable contained a null pointer.
This issue was detected by using the Coccinelle software.

* Thus return directly after a call of the function “kzalloc” failed
  at the beginning.

* Delete an initialisation for the variable “rc”
  which became unnecessary with this refactoring.
