[v2,1/2] nfsd: drop fh argument from alloc_init_deleg

Commit Message

Jeff Layton July 15, 2022, 6:32 p.m. UTC

Currently, we pass the fh of the opened file down through several
functions so that alloc_init_deleg can pass it to delegation_blocked.
The filehandle of the open file is available in the nfs4_file however,
so there's no need to pass it in a separate argument.

Drop the argument from alloc_init_deleg, nfs4_open_delegation and
nfs4_set_delegation.
