Summary

Use bypass to catch any NFS VOP dispatch and route it through the wrapper which does sigdeferstop() and then dispatches original VOP. NFS does not need a bypass below it, which is not supported.

The vop offset in the vop_vector is added since otherwise it is impossible to get vop_op_t from the internal table, and I did not wanted to create the layered fs only to wrap NFS VOPs.

VFS_OP()s wrap is straightforward.

Test Plan

Peter, could you, please, check the change ? NFS is the most interesting case.
