The bio_*_acct functions became GPL exports, which causes the kernel modules to refuse to compile. This replaces code with alternate function calls to the disk_*_io_acct interfaces, which are not GPL exports. This change was added in kernel commit 99dfc43ecbf67f12a06512918aaba61d55863efc. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Coleman Kane <ckane@colemankane.org> Closes #11639
