[net-next 06/16] ixgbevf: Use static inlines instead of macros

From: Mark Rustad <mark.d.rustad@intel.com>

Kernel coding standard prefers static inline functions instead
of macros, so use them for register accessors. This is to prepare
for adding LER, Live Error Recovery, checks to those accessors.
