Subject: [PATCH] xfs: remove redundant re-initialization of total_nr_pages

From: Colin Ian King <colin.king@...onical.com>

Variable total_nr_pages is being initialized and then updated with
the same value, this latter assignment is redundant and can be
removed.  Cleans up clang build warning:

Value stored to 'total_nr_pages' during its initialization is never read
