IB/srpt: Fix ACL lookup during login 

Make sure that the initiator port GUID is stored in ch->ini_guid.
Note: when initiating a connection sgid and dgid members in struct
sa_path_rec represent the source and destination GIDs. When accepting
a connection however sgid represents the destination GID and dgid the
source GID.

Fixes: commit 2bce1a6d22 ("IB/srpt: Accept GUIDs as port names")
