RDMA/bnxt_re: Fix reporting active_{speed,width} attributes

After commit 6d758147 ("RDMA/bnxt_re: Use auxiliary driver interface")
the active_{speed, width} attributes are reported incorrectly, This is
happening because ib_get_eth_speed() is called only once from
bnxt_re_ib_init() - Fix this issue by calling ib_get_eth_speed() from
bnxt_re_query_port().

Fixes: 6d758147 ("RDMA/bnxt_re: Use auxiliary driver interface")
