[PATCH 1/2] NFS: Move definition of enum nfs3_stable_how

Clean up: enum nfs3_stable_how was introduced in NFSv3. NFSv2 has no
stable_how on the wire; its write path passes NFS_FILE_SYNC only as
a placeholder that the protocol ignores. The stable_how constants
describe an NFSv3 wire value, so they belong in linux/nfs3.h.
