slab: make GFP_SLAB_BUG_MASK information more human readable

Browse source 
printk offers %pGg for quite some time so let's use it to get a human
readable list of invalid flags.

The original output would be
  [  429.191962] gfp: 2

after the change
  [  429.191962] Unexpected gfp: 0x2 (__GFP_HIGHMEM)
