[PATCH 03/34] staging: lustre: lnet: change lnet_handle_md_t to proper struct

From: James Simmons
Date: Sun Feb 26 2017 - 20:16:34 EST

Change lnet_handle_md_t from a typedef of another typedef into
a proper stand alone structure. Create the inline functions
LNetInvalidateMDHandle and LNetMDHandleIsInvalid to handle this
new piece of data.
