efd: allow more CPU sockets in table creation

[ upstream commit 8751a7e ]

rte_efd_create() function was using uint8_t for a socket bitmask,
for one of its parameters.
This limits the maximum of NUMA sockets to be 8.
Changing to uint64_t increases it to 64, which should be
more future-proof.

Coverity issue: 366390
Fixes: 56b6ef8 ("efd: new Elastic Flow Distributor library")
