[dpdk-dev] [PATCH v2 3/3] crypto/aesni_gcm: add check for build dependency

The aesni_mb driver has a check in its Makefile for the correct version of
the IPsec_MB library, but this check was missed for the aesni_gcm driver.
Add this check to the makefile, removing an unnecessary assignment in the
process.
