[PATCH] qla2xxx: Pass input-buffer length to Get-ID-List mailbox command.

Browse Source 
Recent ISP24xx firmwares require that mailbox register 8 be
set to the maximum number of bytes to transfer during DMA
copying of the list.  We safely set this value to zero
(infinite), since the call is *only* made in FCAL
topologies.
