[PATCH] tcg: Fix returned type in alloc_code_gen_buffer_splitwx_memfd()

[Shaobo Song <shnusongshaobo@gmail.com>]

 This fixes a bug in POSIX-compliant environments. Since we had allocated 
 a buffer named 'tcg-jit' with read-write access protections we need a int 
 type to combine these access flags and return it, whereas we had inexplicably 
 return a bool type. It may cause an unnecessary protection change in 
 tcg_region_init().
