btrfs: scrub: cleanup the non-RAID56 branches in scrub_stripe()

Browse source

Since we have moved all other profiles handling into their own
functions, now the main body of scrub_stripe() is just handling RAID56
profiles.

There is no need to address other profiles in the main loop of
scrub_stripe(), so we can remove those dead branches.

Since we're here, also slightly change the timing of initialization of
variables like @offset, @increment and @logical.

Especially for @logical, we don't really need to initialize it for
btrfs_extent_root()/btrfs_csum_root(), we can use bg->start for that
purpose.

Now those variables are only initialize for RAID56 branches.
