Alan Somers 420dbe763f gmultipath: make physpath distinct from the underlying providers'
zfsd uses a device's physical path attribute to automatically replace a
missing ZFS disk when a blank disk is inserted into the same physical
slot.  Currently gmultipath passes through its underlying providers'
physical path attribute.  That may cause zfsd to replace a missing
gmultipath provider with a newly arrived, single-path disk.  That would
be bad.

This commit fixes that problem by simply appending "/mp" to the
underlying providers' physical path, in a manner similar to what geli
already does.
