mtd: parser: imagetag: fix error codes in bcm963xx_parse_imagetag_partitions()

[ Upstream commit 12ba8f8ce29fdd277f3100052eddc1afd2f5ea3f ]

If the kstrtouint() calls fail, then this should return a negative
error code but it currently returns success.

Fixes: dd84cb022b31 ("mtd: bcm63xxpart: move imagetag parsing to its own parser")
