[runtime] Don't stash M to stack in arm64 VDSO calls
In fa7ad458444fd2604fb3930aa6b46f12f367dd59, I failed to remove a line
from a previous iteration where I stored the M on the stack. No stack
space is being reserved for the M, which is potentially problematic for
syscalls that don't reserve any space / reserve less than 8 bytes of
space for frame.
