[PATCH 1/4][groovy:linux] cifs: rename reconn_inval_dfs_target()

[Tim Gardner]

From: Paulo Alcantara <pc at cjr.nz>

BugLink: https://bugs.launchpad.net/bugs/1929831

This function has nothing to do with *invalidation* but setting up the
next target server from a cached referral.

Rename it to reconn_set_next_dfs_target().  While at it, get rid of
some meaningless checks.
