[SCSI] libiscsi: fix session age rollover and remove cid encoding
The session age mask is only 4 bits, but session->age is 32. When
it gets larger then 15 and we try to or the bits some bits get
dropped and the check for session age in iscsi_verify_itt is useless.
The ISCSI_CID_MASK related bits are also useless since cid is always
one.
