net/mlx5: E-switch, Respect BW share of the new group

BugLink: https://bugs.launchpad.net/bugs/1953731
[ Upstream commit 1e59b32e45e47c8ea5455182286ba010bfa87813 ]

To enable transmit schduler on vport FW require non-zero configuration
for vport's TSAR. If vport added to the group which has configured BW
share value and TX rate values of the vport are zero, then scheduler
wouldn't be enabled on this vport.
Fix that by calling BW normalization if BW share of the new group is
configured.
