[dpdk-dev] [PATCH 03/10] crypto/null: fix global variable multiple definitions

[Ferruh Yigit <ferruh.yigit@intel.com>]

'null_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: 735b783d8c2b ("crypto/null: add dynamic logging")
