[net-next 01/11] fm10k: reduce scope of the err variable

[Jeff Kirsher]

From: Jacob Keller <jacob.e.kel...@intel.com>

Reduce the scope of the err local variable in the fm10k_dcbnl_ieee_setets
function.

This was detected using cppcheck, and resolves the following style
warning:

[fm10k_dcbnl.c:37]: (style) The scope of the variable 'err' can be reduced.
