[PATCH 1/1] vsprintf: dump full information of page flags in pGp fix

[Yafang Shao]

The name of the flag should be printed using default_str_spec.
There's no difference in the output after this change because the string is
printed as-is with both default_dec_spec and default_flag_spec.

This patch is a followup of the patchset
"mm, vsprintf: dump full information of page flags in pGp" [1]
