[AArch64] Fix checks for AArch64MCExpr::VK_SABS flag.
VK_SABS is part of the SymLoc bitfield in the variant kind which should
be compared for equality, not by checking the VK_SABS bit.
As far as I know, the existing code happened to produce the correct
results in all cases, so this is just a cleanup.
Patch by Stephen Crane.
