block: restore original behavior of /proc/partition when there's no partition

Browse Source 
/proc/partitions didn't use to write out the header if there was no
partition.  However, recent commit 66c64afe changed the behavior.
This is nothing major but there's no reason to change user visible
behavior without a good rationale.  Restore the original behavior.

Note that 2.6.28 has clean up changes scheduled which will replace
this rather hacky implementation.
