Subject: [PATCH -next 1/4] ALSA: rawmidi: Remove unused variable 'dest_frames'

Reported by Clang [-Wunused-but-set-variable]

'commit 08fdced60ca0 ("ALSA: rawmidi: Add framing mode")'
This commit introduced the variable 'dest_frames'.
However this variable was never used except iterates itself.

It seems that it's some undeleted debug code. Remove it for code
cleaning.
