scsi: qla4xxx: Prevent a potential error pointer dereference

Browse Source 
[ Upstream commit 9dcf111dd3e7ed5fce82bb108e3a3fc001c07225 ]

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.
