The only caller of hisi_zip_vf_q_assign() is hidden in an #ifdef,
so the function causes a warning when CONFIG_PCI_IOV is disabled:
drivers/crypto/hisilicon/zip/zip_main.c:740:12: error: unused function 'hisi_zip_vf_q_assign' [-Werror,-Wunused-function]
Replace the #ifdef with an IS_ENABLED() check that leads to the
function being dropped based on the configuration.

The return valude of add_comp_head() is int, but @head_size is size_t,
which is a unsigned type.
size_t head_size;
...
if (head_size < 0) // it will never work
return -ENOMEM
Modify the type of @head_size to int, then change the type to size_t
when invoke hisi_zip_create_req() as a parameter.

HiSilicon ZIP engine supports PCI SRIOV. This patch enable this feature.
User can enable VFs and pass through them to VM, same ZIP driver can work
in VM to provide ZLIB and GZIP algorithm by crypto acomp interface.
