[PATCH] staging: greybus: put macro in a do - while loop

[Dileep Sankhla]

Enclose the macro gb_loopback_stats_attrs defined with multiple
replacement statements in a do - while loop. This avoids possible
if/else logic defects and clears a checkpatch error.

ERROR: Macros with multiple statements should be enclosed in a do -
while loop
