IB/ehca: Fix printk format warnings from u64 type change

Commit fe333321 ("powerpc: Change u64/s64 to a long long integer
type") changed u64 from unsigned long to unsigned long long, which
means that printk formats for printing u64 values should use "ll"
instead of "l" to avoid warnings.  Fix all the places affected by this
in ehca.
