x86/entry: Fix vectors to IDTENTRY_SYSVEC for CONFIG_HYPERV

When assembling with Clang via `make LLVM_IAS=1` and CONFIG_HYPERV enabled,
we observe the following error:

<instantiation>:9:6: error: expected absolute expression
 .if HYPERVISOR_REENLIGHTENMENT_VECTOR == 3
     ^
<instantiation>:1:1: note: while in macro instantiation
idtentry HYPERVISOR_REENLIGHTENMENT_VECTOR asm_sysvec_hyperv_reenlightenment sysvec_hyperv_reenlightenment has_error_code=0
^
./arch/x86/include/asm/idtentry.h:627:1: note: while in macro instantiation
idtentry_sysvec HYPERVISOR_REENLIGHTENMENT_VECTOR sysvec_hyperv_reenlightenment;
^
<instantiation>:9:6: error: expected absolute expression
 .if HYPERVISOR_STIMER0_VECTOR == 3
     ^

^
./arch/x86/include/asm/idtentry.h:628:1: note: while in macro instantiation
idtentry_sysvec HYPERVISOR_STIMER0_VECTOR sysvec_hyperv_stimer0;

This is caused by typos in arch/x86/include/asm/idtentry.h:

HYPERVISOR_REENLIGHTENMENT_VECTOR -> HYPERV_REENLIGHTENMENT_VECTOR
HYPERVISOR_STIMER0_VECTOR         -> HYPERV_STIMER0_VECTOR

For more details see ClangBuiltLinux issue #1088.
