net/mlx5: fix LRO configuration in drop Rx queue

The driver wrongly set the LRO configurations to the TIR of the DevX
drop queue even when LRO is not supported.
Actually, the LRO configuration is not relevant to the drop queue at
all.

This causes failure in the initialization of the device, which doesn't
support LRO where the drop queue is created.

Probably, the drop queue creation by DevX missed the fact that LRO is
set by default in the TIR creation function and didn't unset it in the
drop queue case like other cases that unset LRO.

Move the default LRO configuration to unset it and set it only in the
case of all the TIR queues configured with LRO.
