drivers/crypto: fix build with -fno-common

gcc 10 defaults to -fno-common and as a result when linking
with crypto drivers:

drivers/librte_pmd_dpaa_sec.a(crypto_dpaa_sec_dpaa_sec.c.o):
(.bss+0x4): multiple definition of `rta_sec_era';
drivers/librte_pmd_caam_jr.a(crypto_caam_jr_caam_jr.c.o):
(.bss+0x0): first defined here

drivers/librte_pmd_dpaa2_sec.a(crypto_dpaa2_sec_dpaa2_sec_dpseci.c.o):
(.data+0x0): multiple definition of `rta_sec_era';
drivers/librte_pmd_caam_jr.a(crypto_caam_jr_caam_jr.c.o):
(.bss+0x0): first defined here

This patch fixes the blunt workaround in the following commit.

Fixes: 50b03f3b8eaf ("drivers/crypto: disable gcc 10 no-common errors")
