KVM/arm64 fixes for 6.15, round #3

 - Avoid use of uninitialized memcache pointer in user_mem_abort()

 - Always set HCR_EL2.xMO bits when running in VHE, allowing interrupts
   to be taken while TGE=0 and fixing an ugly bug on AmpereOne that
   occurs when taking an interrupt while clearing the xMO bits
   (AC03_CPU_36)

 - Prevent VMMs from hiding support for AArch64 at any EL virtualized by
   KVM

 - Save/restore the host value for HCRX_EL2 instead of restoring an
   incorrect fixed value

 - Make host_stage2_set_owner_locked() check that the entire requested
   range is memory rather than just the first page
