When determining the current vector length, the SMCR_EL2.LEN and SVCR_EL2.LEN settings should only be considered if EL2 is enabled (compare the pseudocode CurrentSVL and CurrentNSVL which call EL2Enabled()). We were checking against ARM_FEATURE_EL2 rather than calling arm_is_el2_enabled(), which meant that we would look at SMCR_EL2/SVCR_EL2 when in Secure EL1 or Secure EL0 even if Secure EL2 was not enabled. Use the correct check in sve_vqm1_for_el_sm().
