Fix vhost-switch compiling issue when ioat dependency is missing.
Change 'RTE_x86' check into 'RTE_RAW_IOAT' check in meson build file.
Use 'RTE_RAW_IOAT' to control conditional compiling in source file.
Clean some codes.
Fixes: abec60e7115d ("examples/vhost: support vhost async data path")
Fixes: 3a04ecb21420 ("examples/vhost: add async vhost args parsing")

v5:
* Cleaned macro conditional compilation in ioat.c.
v4:
* Use macros in ioat.c for conditional compilation instead of changing
Makefile.
v3:
* Added fixes lines in commit log.
v2:
* Cleaned some codes
* Changed RTE_RAW_IOAT check method in Makefile
* Added ioat function definition when RTE_RAW_IOAT is missing
