bnxt_en: Fix RCU locking for ntuple filters in bnxt_rx_flow_steer()
Similar to the previous patch, RCU locking was released too early
in bnxt_rx_flow_steer(). Fix it to unlock after reading fltr->base.sw_id
to guarantee that fltr won't be freed while we are still reading it.
Fixes: cb5bdd292dc0 ("bnxt_en: Add bnxt_lookup_ntp_filter_from_idx() function")
