net: bnx2x: fix variable dereferenced before check

[ Upstream commit f8885ac89ce310570e5391fe0bf0ec9c7c9b4fdc ]

Smatch says:
	bnx2x_init_ops.h:640 bnx2x_ilt_client_mem_op()
	warn: variable dereferenced before check 'ilt' (see line 638)

Move ilt_cli variable initialization _after_ ilt validation, because
it's unsafe to deref the pointer before validation check.
