  'cpt_logtype' & 'otx_cryptodev_driver_id' global variables are defined
in a header file which was causing multiple definitions of the
variables, fixed it by moving them to the .c file.

Issue has been detected by '-fno-common' gcc flag.

Fixes: bfe2ae495ee2 ("crypto/octeontx: add PMD skeleton")

Hi Ferruh,

This patch could be problematic as our new PMD(crypto_octeontx2) also makes use of some of these. I will propose a new patch with the required changes so that you wouldn't see the mentioned issue. Does that sound ok?

Thanks,
Anoob
