fs-verity: remove unused parameter desc_size in fsverity_create_info()
The parameter desc_size in fsverity_create_info() is useless and it is
not referenced anywhere. The greatest meaning of desc_size here is to
indecate the size of struct fsverity_descriptor and futher calculate the
size of signature. However, the desc->sig_size can do it also and it is
indeed, so remove it.
Therefore, it is no need to acquire desc_size by fsverity_get_descriptor()
in ensure_verity_info(), so remove the parameter desc_ret in
fsverity_get_descriptor() too.
