[PATCH 6/7] fs/ext4: use sleeping version of sb_find_get_block()

[Davidlohr Bueso <dave@stgolabs.net>]

Enable ext4_free_blocks() to use it, which has a cond_resched to begin
with. Convert to the new nonatomic flavor to benefit from potential
performance benefits and adapt in the future vs migration such that
semantics are kept.
