[PATCH] mtd: Fix physmap_of to not exit upon unsuccessful partition scan

[Stefan Roese <sr@denx.de>]

The patch 9a310d21196f38f6ad0ad146057548653e495c09 ("[MTD] Factor out OF
partition support from the NOR driver.") introduced an problem. Now the
physmap_of driver returns with error upon the first unsuccessful
partition scan (parse_mtd_partitions()). This is not wanted, since even
when the RedBoot/cmdlinepart partition scan is unsuccessful, the other
scan's (of_mtd_parse_partitions(), parse_obsolete_partitions()) should be
done nevertheless.

This patch fixes this problem.

Scott, could you please take a look at this patch and add you ACK if you
think it is ok?

Thanks.
