Tyler Hicks 60d4885710 binder: take read mode of mmap_sem in binder_alloc_free_page() ... Restore the behavior of locking mmap_sem for reading in binder_alloc_free_page(), as was first done in commit 3013bf62b6 ("binder: reduce mmap_sem write-side lock"). That change was inadvertently reverted by commit 5cec2d2e58 ("binder: fix race between munmap() and direct reclaim"). In addition, change the name of the label for the error path to accurately reflect that we're taking the lock for reading. Backporting note: This fix is only needed when *both* of the commits mentioned above are applied. That's an unlikely situation since they both landed during the development of v5.1 but only one of them is targeted for stable.
