IB/hns: Modify the macro for the timeout when cmd process 

This patch modified the macro for the timeout when cmd is
processing as follows:
Before modification:
 enum {
	HNS_ROCE_CMD_TIME_CLASS_A       = 10000,
	HNS_ROCE_CMD_TIME_CLASS_B       = 10000,
	HNS_ROCE_CMD_TIME_CLASS_C       = 10000,
 };
After modification:
 #define HNS_ROCE_CMD_TIMEOUT_MSECS	10000
