falco: Falco failing to start with kernel module not loaded

Describe the bug Falco failing to start

[root /]# /usr/bin/falco-driver-loader --compile
* Running falco-driver-loader for: falco version=0.33.0, driver version=3.0.1+driver, arch=x86_64, kernel release=4.18.0-372.26.1.el8_6.x86_64, kernel version=1
* Running falco-driver-loader with: driver=module, compile=yes, download=no

================ Cleaning phase ================

* 1. Check if kernel module 'falco' is still loaded:
- Kernel module 'falco' is still loaded.
- Trying to unload it with 'rmmod falco'...
- OK! Unloading 'falco' module succeeded.

* 2. Check all versions of kernel module 'falco' in dkms:
- There are some versions of 'falco' module in dkms.

* 3. Removing all the following versions from dkms:
3.0.1+driver

- Removing 3.0.1+driver...
Deleting module falco-3.0.1+driver completely from the DKMS tree.

- OK! Removing '3.0.1+driver' succeeded.


[SUCCESS] Cleaning phase correctly terminated.
