CHROMIUM: android: binder: Fix potential scheduling-while-atomic
(cherry picked from commit 166b45af97359159f9585a836c9849e725e31fd6)
Commit f1e7f0a724f6 ("android: binder: Disable preemption while holding
the global binder lock.") re-enabled preemption around most of the sites
where calls to potentially sleeping functions were made, but missed
__alloc_fd(), which can sleep if the fdtable needs to be resized.
Re-enable preemption around __alloc_fd() as well as __fd_install() which
can now sleep in upstream kernels as of commit 8a81252b774b ("fs/file.c:
don't acquire files->file_lock in fd_install()").
BUG=chrome-os-partner:44012
TEST=Build and boot on Smaug.
