Subject: [PATCH V4 7/9] rpmsg: glink: Remove chunk size word align warning

From: Chris Lew <clew@...eaurora.org>

It is possible for the chunk sizes coming from the non RPM remote procs
to not be word aligned. Remove the alignment warning and continue to
read from the FIFO so execution is not stalled.
