The check against VSID range is implied when we check task size against
hash and radix pgtable range[1], because we make sure page table range cannot
exceed vsid range.

[1] BUILD_BUG_ON(TASK_SIZE_USER64 > H_PGTABLE_RANGE);
BUILD_BUG_ON(TASK_SIZE_USER64 > RADIX_PGTABLE_RANGE);

The check for smaller task size is also removed here, because the follow up
patch will support a tasksize smaller than pgtable range.
