net: hns3: fix tm port shapping of fibre port is incorrect after driver initialization

Currently in driver initialization process, driver will set shapping
parameters of tm port to default speed read from firmware. However, the
speed of SFP module may not be default speed, so shapping parameters of
tm port may be incorrect.

To fix this problem, driver sets new shapping parameters for tm port
after getting exact speed of SFP module in this case.
