[PATCH 2/4] scsi: lpfc: Return directly after a failed kzalloc() in lpfc_sli_read_link_ste()

The kfree() function was called in one case by
the lpfc_sli_read_link_ste() 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.
