IB/hfi1: Fix a memleak in init_credit_return

Browse Source 
[ Upstream commit 809aa64ebff51eb170ee31a95f83b2d21efa32e2 ]

When dma_alloc_coherent fails to allocate dd->cr_base[i].va,
init_credit_return should deallocate dd->cr_base and
dd->cr_base[i] that allocated before. Or those resources
would be never freed and a memleak is triggered.
