media: atomisp: Remove unnecessary msleep(10) from atomisp_mrfld_power() error path

Remove unnecessary msleep(10) from atomisp_mrfld_power() error-exit path,
the success exit from atomisp_mrfld_power() happens if a test succeeds
inside the do { } while loop above the msleep().

The error-exit path with the removed msleep is only hit it the power-on is
not reflected in the iUNIT ISPSSPM0 status bits after a timeout of 50 ms.
Sleeping an extra 10 ms in the timeout path makes little sense.
