ext4: fix check of inode in swap_inode_boot_loader
commit 67a11611e1a5211f6569044fbf8150875764d1d0 upstream. Before really do swap between inode and boot inode, something need to check to avoid invalid or not permitted operation, like does this inode has inline data. But the condition check should be protected by inode lock to avoid change while swapping. Also some other condition will not change between swapping, but there has no problem to do this under inode lock.
