slub: Move gfpflag masking out of the hotpath
Move the gfpflags masking into the hooks for checkers and into the slowpaths. gfpflag masking requires access to a global variable and thus adds an additional cacheline reference to the hotpaths. If no hooks are active then the gfpflag masking will result in code that the compiler can toss out.
