Introduce a common helper to consolidate stripe validation process.
Also make kernel code xfs_validate_sb_common() use it first.

Signed-off-by: Gao Xiang <hsiangkao@redhat.com>

v2: https://lore.kernel.org/r/20201013034853.28236-1-hsiangkao@redhat.com

Changes since v2:
 - update the expression on sb_unit and hasdalign check (Brian);
 - drop parentheses since modulus operation is a basic
   math operation (Brian);
 - (I missed earlier..) avoid div_s64_rem on modulus operation
   by checking swidth, sunit range first and casting to 32-bit
   integer. since sunit/swidth in the callers are in FSB or BB,
   so need to check the overflow first...

 Anyway, since logic change is made due to div_s64_rem() issue,
 please kindly help review again...

Thanks,
Gao Xiang
