MD RAID10: Export md_raid10_congested
md/raid10: Export is_congested test.
In similar fashion to commits
11d8a6e3719519fbc0e2c9d61b6fa931b84bf813

we export the RAID10 congestion checking function so that dm-raid.c can
make use of it and make use of the personality. The 'queue' and 'gendisk'
structures will not be available to the MD code when device-mapper sets
up the device, so we conditionalize access to these fields also.
