[PATCH] net/intel: rename variable in Rx select to improve clarity

[PATCH] net/intel: rename variable in Rx select to improve clarity

[Ciara Loftus]

The common rx path selection function contains logic that compares two
rx paths:
1. the path selected as most suitable so far aka "current path"
2. a candidate path that has not yet been selected aka "path"

This naming could cause confusion, as the candidate path could also be
considered the "current path". To rectify this, rename "current path" to
"chosen path".
