IB/core: Refer to RoCE port property instead of GID table property

ib_query_gid() in commit [1] refers to RoCE GID table capability of
the HCA using rdma_cap_roce_gid_table().
ib_core maintains the GID table cache regardless of the HCA provider
drivers capability to maintain RoCE GID table.
Therefore, whether to return a GID table entry from the software cache or
from HCA should be done based on whether the port is RoCE or not.
