cputlb: remove useless arguments to tlb_unprotect_code_phys, rename
These days modification of the TLB is done in notdirty_mem_write,
so the virtual address and env pointer as unnecessary.

The new name of the function, tlb_unprotect_code, is consistent with
tlb_protect_code.

Backports commit 9564f52da7eb061326956ed9a468935e3352512d from qemu
