igc: Remove delay during TX ring configuration

Browse Source 
[ Upstream commit cca28ceac7c7857bc2d313777017585aef00bcc4 ]

Remove unnecessary delay during the TX ring configuration.
This will cause delay, especially during link down and
link up activity.

Furthermore, old SKUs like as I225 will call the reset_adapter
to reset the controller during TSN mode Gate Control List (GCL)
setting. This will add more time to the configuration of the
real-time use case.

It doesn't mentioned about this delay in the Software User Manual.
It might have been ported from legacy code I210 in the past.
