IB: Move the macro IB_UMEM_MAX_PAGE_CHUNK() to umem.c
After moving the definition of struct ib_umem_chunk from ib_verbs.h to ib_umem.h there isn't any reason for the macro IB_UMEM_MAX_PAGE_CHUNK to stay in ib_verbs.h. Move the macro to umem.c, the only place where it is used. Signed-off-by: Dotan Barak <dotanb@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
