vboot/vboot_kernel: fix various style issues

Change conditional checks to match other vboot code.
Instead of:

  if (rv != VB2_SUCCESS)

Just use:

  if (rv)

Also fix up spacing on a vb2_load_partition call.

This CL is part of a series to merge vboot1 and vboot2.0
kernel verification code; see b/181739551.
