fuse: Grab the fc->lock for inode updates in passthrough
The function fsstack_copy_inode_size uses the inode->i_lock to
serialize the inode updates. This lock is not used in the FUSE
filesystem and thus it is not enough to just grab this lock
before updating a FUSE inode.
Grab the fc->lock for inode updates in passthrough to ensure
that there are no races between inode size updates in 32 bit
architectures with SMP.
