qlcnic: refactor Tx/SDS ring calculation and validation in driver.
o Current driver has duplicate code for validating user input
for changing Tx/SDS rings using set_channel ethtool interface.
This patch removes duplicate code and refactored Tx/SDS ring
validation for 82xx/83xx/84xx series adapter.
o Refactored code now calculates maximum Tx/Rx ring driver can
support based on Default, NPAR and SRIOV PF/VF mode of driver.
