md/md-bitmap: remove unnecessary local variable in backlog_store()

Browse Source 
[ Upstream commit b4d129640f194ffc4cc64c3e97f98ae944c072e8 ]

Local variable is definied first in the beginning of backlog_store(),
there is no need to define it again.

Fixes: 8c13ab115b ("md/bitmap: don't set max_write_behind if there is no write mostly device")
