Fix a "scheduling while atomic" locking bug in uio.  Original
bug-reporter has verified that this patch resolves the problem.

Weird bit: The fix for this landed in mainline lumped into another
commit -- a revert of a commit that Bionic doesn't actually carry.
This patch for Bionic is a "backport" of that mainline revert,
picking up just that lumped-in part from the revert.
