Unconditionally load core kernel modules
Loading and unloading the zlib modules as part of the zfs.sh script has proven a little problematic for a few reasons. * First, your kernel may not need to load either zlib_inflate or zlib_deflate. This functionality may be built directly in to your kernel. It depends entirely on what your distribution decided was the right thing to do. * Second, even if you do manage to load the correct modules you may not be able to unload them. There may other consumers of the modules with a reference preventing the unload. To avoid both of these issues the test scripts have been updated to attempt to unconditionally load all modules listed in KERNEL_MODULES. If the module is successfully loaded you must have needed it. If the module can't be loaded that almost certainly means either it is built in to your kernel or is already being used by another consumer. In both cases this is not an issue and we can move on to the spl/zfs modules. Finally, by removing these kernel modules from the MODULES list we ensure they are never unloaded during 'zfs.sh -u'. This avoids the issue of the script failing because there is another consumer using the module we were not aware of. In other words the script restricts unloading modules to only the spl/zfs modules. Closes #78
