 Fix regression in GFP output in trace events
 
 It was reported that the GFP flags in trace events went from human
 readable to just their hex values:
 
   gfp_flags=GFP_HIGHUSER_MOVABLE|__GFP_COMP to gfp_flags=0x140cca
 
 This was caused by a change that added the use of enums in calculating
 the GFP flags. As defines get translated into their values in the
 trace event format files, the user space tooling could easily convert
 the GFP flags into their symbols via the __print_flags() helper macro.
 The problem is that enums do not get converted, and the names of the
 enums show up in the format files and user space tooling cannot translate
 them.
 
 Add TRACE_DEFINE_ENUM() around the enums used for GFP flags which is the
 tracing infrastructure macro that informs the tracing subsystem what
 the values for enums and it can then expose that to user space.
