LU-9311 pfl: shouldn't reprocess granted resent request

When the LOVEA buffer is bigger than the request reply buffer, the
client will resend the layout write intent RPC, and
mdt_layout_change() should not reprocess it since the 2nd process
will try to cancel the 1st granted CR lock, while client has not
get it granted yet because of the reply buffer shortage resend the
RPC.

This patch also adjusts some debug messages, makes dump_lsm() dump
uninstantiated component stripe info.
