badblocks: fix the using of MAX_BADBLOCKS

Browse Source 
The number of badblocks cannot exceed MAX_BADBLOCKS, but it should be
allowed to equal MAX_BADBLOCKS.

Fixes: aa511ff821 ("badblocks: switch to the improved badblock handling code")
Fixes: c3c6a86e9e ("badblocks: add helper routines for badblock ranges handling")
