Coly Li 146e843f6b badblocks: avoid checking invalid range in badblocks_check() 
If prev_badblocks() returns '-1', it means no valid badblocks record
before the checking range. It doesn't make sense to check whether
the input checking range is overlapped with the non-existed invalid
front range.

This patch checkes whether 'prev >= 0' is true before calling
overlap_front(), to void such invalid operations.

Fixes: 3ea3354cb9f0 ("badblocks: improve badblocks_check() for multiple ranges handling")
