Ferruh Yigit 4d6194db01 compress/octeontx: fix global variable multiple definitions 
'octtx_zip_logtype_driver' global variable is defined in a header file
which was causing multiple definitions of the variable, fixed it by
moving it to the .c file.

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

Fixes: 43e610bb85 ("compress/octeontx: introduce octeontx zip PMD")
