net/mlx5: increase async EQ to avoid EQ overrun
Currently the async EQ has 256 entries only. It might not be big enough for the SW to handle all the needed pending events. For example, in case of many QPs (let's say 1024) connected to a SRQ created using NVMeOF target and the target goes down, the FW will raise 1024 "last WQE reached" events and may cause EQ overrun. Increase the EQ to more reasonable size, that beyond it the FW should be able to delay the event and raise it later on using internal backpressure mechanism.
