[PATCH] md: Fix a bug that recently crept into md/linear

A recent patch that allowed linear arrays to be reconfigured on-line
allowed in a bug which results in divide by zero - not all
mddev->array_size were converted to conf->array_size.

This patch finished the conversion and fixed the bug.

The offending patch was commit 7c7546ccf6463edbeee8d9aac6de7be1cd80d08a.

Thanks to Simon Kirby <sim@netnation.com> for the bug report.
