target/arm: Initialize ARMMMUFaultInfo in v7m_stack_read/write
The get_phys_addr() functions take a pointer to an ARMMMUFaultInfo struct, which they fill in only if a fault occurs. This means that the caller must always zero-initialize the struct before passing it in. We forgot to do this in v7m_stack_read() and v7m_stack_write(). Correct the error.
