[PATCH 4.18 046/350] selftests: usbip: add wait after attach and before checking port status

[Greg Kroah-Hartman]

4.18-stable review patch.  If anyone has any objections, please let me know.

[ Upstream commit 4b0aaacee51eb6592a03fdefd5ce97558518e291 ]

Add sleep between attach and "usbip port" check to make sure status is
updated. Running attach and query back shows incorrect status.
