[PATCH v1 27/30] fuse: rename fuse_set_zero_arg0() to fuse_zero_in_arg0()

[Joanne Koong <joannelkoong@gmail.com>]

The fuse_set_zero_arg0() function is used for setting a no-op header for
in args but to support fuse io-uring zero-copy, the first parameter of
outargs will also need to be set to a no-op header if the request
contains payload but no out heeader.

Rename fuse_set_zero_arg0() to fuse_zero_in_arg0() to indicate this is
for the in arg header. Later, fuse_zero_out_arg0() will be added.
