When using CM to establish connections, qp number that was freed
just now will be rejected by ib core. To fix these problem, We
change qpn allocation to round-robin mode. We added the round-robin
mode for allocating resources using bitmap. We use round-robin mode
for qp number and non round-robing mode for other resources like
cq number, pd number etc.

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

This patch modified the logic of allocating memory using APIs in
hns RoCE driver. We used kcalloc instead of kmalloc_array and
bitmap_zero. And When kcalloc failed, call vzalloc to alloc
memory.

While the page size attribute of umem is illegal, we should release
umem that get by ib_umem_get interface.

Also, we should return a non-zero value while pbl number is wrong.
