KVM: arm64: Get sys_reg encoding from descriptor in idregs_debug_show()

Browse Source 
KVM is about to add support for more VM-scoped feature ID regs that
live outside of the id_regs[] array, which means the index of the
debugfs iterator may not actually be an index into the array.

Prepare by getting the sys_reg encoding from the descriptor itself.
