ppc/pnv: fix check on return value of blk_getlength()
blk_getlength() returns an int64_t but the result is stored in a uint32_t. Errors (negative values) won't be caught by the check in pnv_pnor_realize() and blk_blockalign() will allocate a very large buffer in such cases. Fixes Coverity issue CID 1412226.
