[Intel-gfx] [PATCH v8 13/16] mei: drop ready bits check after start

From: Alexander Usyskin <alexander.usyskin at intel.com>

The check that hardware and host ready bits are set after start
is redundant and may fail and disable driver if there is
back-to-back link reset issued right after start.
This happens during pxp mode transitions when firmware
undergo reset. Remove these checks to eliminate such failures.
