Subject: [PATCH] arm64: kvm: Delete duplicated label: in invalid_vector

SYM_CODE_START defines \label , so it is redundant to define \label again.
A redefinition at the same place is accepted by GNU as
(https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=159fbb6088f17a341bcaaac960623cab881b4981)
but rejected by the clang integrated assembler.

Fixes: 617a2f392c92 ("arm64: kvm: Annotate assembly using modern annoations")
