qla2xxx: Enable Extended Logins support

Browse Source 
This patch enables Extended Logins support in Qlogic ISP.
To enable extended login with Qlogic ISP24XX/25XX/26XX,
set module parameter ql2xexlogins to any non-zero number.
This will alow ISP firmware to store port database structure
information of remote login sessions to host memory provided
by driver. ISP firmware supports upto 16k total logins.
