Subject: fm10k: reduce scope of the ring variable
Patch-mainline: v5.4-rc1
Git-commit: df87b8fcf8fe658518fa8e75c9379e5bdfaf908c
References: jsc#SLE-8009

Reduce the scope of the ring local variable in the fm10k_assign_l2_accel
function.

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

[fm10k_netdev.c:1447]: (style) The scope of the variable 'ring' can be
reduced.
