accel/ivpu: Fix wrong register read in LNL failure diagnostics
diagnose_failure_lnl() read VPU_HW_BTRS_MTL_INTERRUPT_STAT instead of
VPU_HW_BTRS_LNL_INTERRUPT_STAT, which on LNL and newer parts is a
different register with a different bit layout, so failure diagnostics
decoded the wrong register and reported a bogus error cause.
Read the LNL interrupt status register instead.
