powerpc: Rely on address instead of pte_user()
pte_user() may return 'false' when a user page is PAGE_NONE.
In that case it is still a user page and needs to be handled
as such. So use is_kernel_addr() instead.
And remove "user" text from ptdump as ptdump only dumps
kernel tables.
Note: no change done for book3s/64 which still has it
'priviledge' bit.
