md/raid5: avoid redundant bio clone in raid5_read_one_chunk

mainline inclusion
from mainline-v5.14-rc1
commit 1147f58e
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I587H6
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=1147f58e1010b8688bac1fd3bbab753b1379291d



-------------------------------

After enable io accounting, chunk read bio could be cloned twice which
is not good. To avoid such inefficiency, let's clone align_bio from
io_acct_set too, then we need only call md_account_bio in make_request
unconditionally.
