I am experiencing the same issue.  CentOS 7 /w kernel 3.10.0-957.1.3.el7.x86_64.  Let me know if there is any additional information I can provide that would be helpful.

DAHDI 3.0 will only compile on kernels 4.15 or newer.

"The setup_timer functions were removed in upstream kernel v4.15, and therefore
this change is needed in order to compile DAHDI for kernels >= 4.15."

Use DAHDI 2.11.1 for older kernels.
