This reverts commit 2e42b7f817acd6e8d78226445eb6fe44fe79c12a. If the GC victim section has a pinned block when fallocate() trigger FG_GC, the section is not able to be recycled. And this will return -EAGAIN cause fallocate() failed, even though there are much spare space as user see. As the GC policy prone to chose the same victim, fallocate() may not successed at a long period. This scenario has been found during Android OTA.
