qla2xxx: Disable out-of-order processing by default in firmware
Out of order(OOO) processing requires initiator, switch
and target to support OOO. In today's environment, none
of the switches support OOO. OOO requires extra buffer
space which affect performance. By turning ON this feature
in QLogic's FW, it delays error recovery because dropped
frame is treated as out of order frame. We're turning OFF
this option of speed up error recovery.
