unexport d_alloc_pseudo()
No modular uses since introducion of alloc_file_pseudo(),
and the only non-modular user not in alloc_file_pseudo()
had actually been wrong - should've been d_alloc_anon().

DCACHE_RCUACCESS is gone; having an RCU delay on dentry freeing is the
default. DCACHE_NORCU opts out, and only d_alloc_pseudo() has any
business doing so.
