net/mlx5: Bridge, refactor eswitch instance usage 

Several functions in bridge.c excessively obtain pointer to parent eswitch
instance by dereferencing br_offloads->esw on every usage and following
patches in this series add even more usages of eswitch. Introduce local
variable 'esw' and use it instead.
