NFSD: use (un)lock_inode instead of fh_(un)lock for file operations

When locking a file to access ACLs and xattrs etc, use explicit locking
with inode_lock() instead of fh_lock().  This means that the calls to
fh_fill_pre/post_attr() are also explicit which improves readability and
allows us to place them only where they are needed.  Only the xattr
calls need pre/post information.

When locking a file we don't need I_MUTEX_PARENT as the file is not a
parent of anything, so we can use inode_lock() directly rather than the
inode_lock_nested() call that fh_lock() uses.
