Bug fix in qat_compress.c for vmalloc addr check
Remove the unused vmalloc address check, and function mem_to_page will handle the non-vmalloc address when map it to a physical address. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Weigang Li <weigang.li@intel.com> Closes #7125
