netfs: Fix potential for tearing in ->remote_i_size and ->zero_point

In the Linux kernel, the following vulnerability has been resolved:

netfs: Fix potential for tearing in ->remote_i_size and ->zero_point

Fix potential tearing in using ->remote_i_size and ->zero_point by copying
i_size_read() and i_size_write() and using the same seqcount as for i_size.

We need to make sure that netfslib and the filesystems that use it always
hold i_lock whilst updating any of the sizes to prevent i_size_seqcount
from getting corrupted.
