[RFC PATCH 15/19] net/i40e: fix build with shadow warnings enabled

[Bruce Richardson <bruce.richardson@intel.com>]

The local variables defined with the I40E_WRITE_GLB_REG macro are
shadowing other variables. Rename the vars to start with "_" to avoid
this shadowing.

Fixes: 2bedd7277a10 ("net/i40e: print real global changes")
