[PATCH 1/2] pstore: fix build by re-resolving botched merge conflict

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

297ac7288 ("pstore: Only capture log messages") removed the pstore console.
v3 of the eventually merged 75a74b5c ("console: fix out-of-bounds read
in dputc(/dev/*, ...)") reinstated part of this code, which broke the
pstore build because the now removed bufsize member had a user
reintroduced in the patch.

Fix this by reverting the offending patch's changes to the pstore code.
It wasn't applicable to begin with.

Fixes: 75a74b5c ("console: fix out-of-bounds read in dputc(/dev/*, ...)")

Hello Sascha,

I broke pstore in v2019.10.0 because of the botched merge conflict
resolve described above. Can this patch be applied to master?

Thanks,
Ahmad
