LOG: [AArch64] Fix unused-variable warning for non-dbg builds. (#143175)

AArch64ISelLowering.cpp currently fails -Wunused-variable because SrcVT
is only used in assert(), so it is an unused variable if not using debug
builds. This behavior was introduced in 2c0a2261.

Added: 
    

Modified: 
    llvm/lib/Target/AArch64/AArch64ISelLowering.cpp

Removed:
