RDMA/hns: Fix usage of bitmap allocation functions return values
hns bitmap allocation functions return 0 on success and -1 on failure.
Callers of these functions wrongly used their return value as an errno,
fix that by making a proper conversion.
Fixes: a598c6f4c5a8 ("IB/hns: Simplify function of pd alloc and qp alloc")
