Subject: [net-next 07/11] fm10k: reduce the scope of the err variable

From: Jacob Keller <jacob.e.keller@...el.com>

Reduce the scope of the local variable err in the fm10k_detach_subtask
function.

This was detected by cppcheck and resolves the following warning
produced by that tool:

[fm10k_pci.c:403]: (style) The scope of the variable 'err' can be reduced.
