emulex/benet: correct command version selection in be_cmd_get_stats()

[ Upstream commit edb888d29748cee674006a52e544925dacc7728e ]

Logic here always sets hdr->version to 2 if it is not a BE3 or Lancer chip,
even if it is BE2. Use 'else if' to prevent multiple assignments, setting
version 0 for BE2, version 1 for BE3 and Lancer, and version 2 for others.
Fixes potential incorrect version setting when BE2_chip and
BE3_chip/lancer_chip checks could both be true.
