[PATCH] staging: lustre: remove IOC_LIBCFS_PING_TEST ioctl

[y]

From: James Simmons <uja.ornl@yahoo.com>

The ioctl IOC_LIBCFS_PING_TEST has not been used in
ages. The recent nidstring changes which moved all
the nidstring operations from libcfs to the LNet
layer but this ioctl code was still using an
nidstring operation that was causing an circular
dependency loop between libcfs and LNet.
