io_uring: use bottom half safe lock for fixed file data
commit ac0648a56c1ff66c1cbf735075ad33a26cbc50de upstream.
io_file_data_ref_zero() can be invoked from soft-irq from the RCU core,
hence we need to ensure that the file_data lock is bottom half safe. Use
the _bh() variants when grabbing this lock.
