jbd2: Fix statistics for the number of logged blocks

Browse Source 
[ Upstream commit 015c6033068208d6227612c878877919f3fcf6b6 ]

jbd2 statistics counting number of blocks logged in a transaction was
wrong. It didn't count the commit block and more importantly it didn't
count revoke descriptor blocks. Make sure these get properly counted.
