Fixed incorrect modulus in lfs_alloc_reset

Browse Source 
Modulus of the offset by block_size was clearly a typo, and should be
block_count. Interesting to note that later moduluses during alloc
calculations prevents this from breaking anything, but as gtaska notes it
could skew the wear-leveling distribution.
