security/vboot: Drop assert call from vbnv_udc_enable_flag()
It's true that vbnv_udc_enable_flag() is called after vbnv_init()
(that's why the assertion was added). However, the former is called in
the ramstage, while the latter in verstage. This means that
vbnv_initialized will be false in ramstage, which leads
to the assertion failure:
[EMERG] ASSERTION ERROR: file 'src/security/vboot/vbnv.c', line 88
Since the ctx->nvdata will be restored in ramstage (by vb2api_reinit()),
simply remove the assertion. So, the patch drops assert call from
vbnv_udc_enable_flag() function.
TEST=Verify Rex system boots to OS without assert error.
