[PATCH] md/bitmap: tidy up i_writecount handling in md/bitmap

Browse Source 
md/bitmap modifies i_writecount of a bitmap file to make sure that no-one else
writes to it.  The reverting of the change is sometimes done twice, and there
is one error path where it is omitted.

This patch tidies that up.
