x86/asm/msr: Make wrmsrl() a function
As of cf991de2f614 ("x86/asm/msr: Make wrmsrl_safe() a function"), wrmsrl_safe is a function, but wrmsrl is still a macro. The wrmsrl macro performs invalid shifts if the value argument is 32 bits. This makes it unnecessarily awkward to write code that puts an unsigned long into an MSR. To make this work, syscall_init needs tweaking to stop passing a function pointer to wrmsrl.
