[PATCH 2/2] mtd: Remove the no longer need functions, check_free_sectors and memcmpb

[Nicholas Krause]

The functions,check_free_sectors and memcmpb are no longer needed due to
removing the only caller for both functions in check_free_sectors for
memcmpb and in INFTL_formatblock for check_free_sectors respectfully.
