  [AArch64][SME] Fix iterator to fixupCalleeSaveRestoreStackOffset (#110855)

The iterator passed to `fixupCalleeSaveRestoreStackOffset` may be
incorrect when it tries to skip over the instructions that get the
current value of 'vg', when there is a 'rdsvl' instruction straight
after the prologue. That's because it doesn't check that the instruction
is still a 'frame-setup' instruction.
