[PATCH 3/3] page-flags: rectify forward declaration

[Sudip Mukherjee <sudipm.mukherjee@gmail.com>]

compound_head is defined as inline in page-flags.h but in the forward
declaration of compound_head in the same file missed "inline". As a result
we got plenty of build warnings while building for some architecture
like avr32. The warning showed as:
warning: 'compound_head' declared inline after being called.
warning: previous declaration of 'compound_head' was here

tested build with avr32 and also with x86_64 allmodconfig to verify that
nothing breaks due to this change.
