drivers/mrc_cache: Fix size comparison in mrc_cache update
`mrc_cache_needs_update` is comparing the "new size" of the MRC data (minus metadata size) to the size including the metadata, which causes the driver to think the data has changed, and so it will rewrite the MRC cache on every boot. This patch removes the metadata size from the comparison. BUG=b:171513942 BRANCH=volteer TEST=1) Memory training data gets written the on a boot where the data was wiped out. 2) Memory training data does not get written back on every subsequent boot.
