[Xen-devel] [BLKTAP]: Kill duplicate fast_flush_area call

[Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx>]

Hi Keir:

[BLKTAP]: Kill duplicate fast_flush_area call

The dispatch_rw_block_io may call fast_flush_area twice if
create_lookup_pte_addr fails (there is a flush call at fail_flush
already).  The second call simply causes warnings to be printed
on the console.  This patch removes the duplicate call.

Cheers,
