[PATCH] mtd: mtdparts: calculate mtd partition offset before calculating size

[Weijie Gao]

The mtd partition offset must be calculated first as it will be
referenced when calculating the mtd partition size.

Change-Id: Iccfd101b0a9597ac240c25670da638a82af28980
Fixes: 1ca97ee9039 (mtd: mtdpart: Support MTD_SIZE_REMAINING with unallocated 
memory area)
