RDMA/bnxt_re: Fix reporting active_{speed,width} attributes
[ Upstream commit 18e7e3e4217083a682e2c7282011c70c8a1ba070 ]
After commit 6d758147c7b8 ("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: 6d758147c7b8 ("RDMA/bnxt_re: Use auxiliary driver interface")
