ice: fix pre-shifted bit usage
While converting to FIELD_PREP() and FIELD_GET(), it was noticed that
some of the RSS defines had *included* the shift in their definitions.
This is completely outside of normal, such that a developer could easily
make a mistake and shift at the usage site (like when using
FIELD_PREP()).
Rename the defines and set them to the "pre-shifted values" so they
match the template the driver normally uses for masks and the member
bits of the mask, which also allows the driver to use FIELD_PREP
correctly with these values. Use GENMASK() for this changed MASK value.
Do the same for the VLAN EMODE defines as well.
