This reverts commit 6d7855c54e1e269275d7c504f8f62a0b7a5b3f18.

The commit 6d7855c54e1e ("sockfs: switch to ->free_inode()") made the
deallocation of 'socket_alloc' to be done asynchronously using RCU, as
same to 'sock.wq'.

The change made 'socket_alloc' live longer than before.  As a result,
user programs intensively repeating allocations and deallocations of
sockets could cause memory pressure on recent kernels.

To avoid the problem, this commit reverts the change.
