rGcfb3a1dee11c: ixgbe(4): Fix enabling/disabling and reconfiguration of queues
rS350253: ixgbe(4): Fix enabling/disabling and reconfiguration of queues

Summary

Wrong order of casting and bit shift caused that enabling and disabling queues didn't work properly for queues number larger than 32. Use literals with right suffix instead.
TX ring tail address was not updated during reinitiailzation of TX structures. It could block sending traffic.
Also remove unused variables 'eims' and 'active_queues'.

Test Plan

Respectfully requesting our Validation Team to perform a test pass before committing.
