Subject: [PATCH 14/17] usb: vhci-hcd: Consistently use __func__

Replace all explicit function names in string literals with __func__ and
silent several checkpatch complaints similar to the following one:

  WARNING: Prefer using '"%s...", __func__' to using 'vhci_start', this function's name, in a string

In case of the usbip_dbg_*() helpers, which are wrappers over
pr_debug(), the function names end up duplicated, hence replace the
superfluous strings with some useful info or simply drop the log entries
altogether if they become ftrace-like.
