fs/ext4: use sleeping version of sb_find_get_block()

[ Upstream commit 6e8f57fd09c9fb569d10b2ccc3878155b702591a ]

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.
