Coleman Kane d08b99aca0 Linux 5.16: bio_set_dev is no longer a helper macro ... This change adds a confiugre check to determine if bio_set_dev is a helper macro or not. If not, then the attempt to override its internal call to bio_associate_blkg(), with a macro definition to our own version, is no longer possible, as the compiler won't use it when compiling the new inline function replacement implemented in the header. This change also creates a new vdev_bio_set_dev() function that performs the same work, and also performs the work implemented in vdev_bio_associate_blkg(), as it is the only thing calling that function in our code. Our custom vdev_bio_associate_blkg() is now only compiled if the bio_set_dev() is a macro in the Linux headers.
