[PATCH RFC v2 1/5] NFS: name the init_nfs_fs() error labels

[Chuck Lever <cel@kernel.org>]

The unwind labels in init_nfs_fs() are numbered, and the numbering
already skips out8, so a reader has to count the label block to
learn what each one undoes. Inserting an init step means either
renumbering every label below it or leaving the sequence out of
order, and a goto that picks the wrong number unwinds the wrong
step.

Name each label for the step it undoes, as coding-style.rst asks.
