CVE-2025-39676

In the Linux kernel, the following vulnerability has been resolved:

scsi: qla4xxx: Prevent a potential error pointer dereference

The qla4xxx_get_ep_fwdb() function is supposed to return NULL on error,
but qla4xxx_ep_connect() returns error pointers.  Propagating the error
pointers will lead to an Oops in the caller, so change the error pointers
to NULL.
