parentIB/ipath: Make ipath_portdata work with struct pid * not pid_t (diff)

IB/ipath: Change ipath_devdata.ipath_sdma_status to be unsigned long
Andrew Morton <akpm@linux-foundation.org> pointed out that bitops should take an unsigned long * arg. However, the ipath driver was doing bitops on struct ipath_devdata.ipath_sdma_status, which is u64. Change this member to unsigned long to avoid tons of warnings when x86 fixes the bitops to take unsigned long * instead of void *. Also, change the IPATH_SDMA_RUNNING and IPATH_SDMA_SHUTDOWN bit numbers to 30 and 31 (instead of 62 and 63) so that we're not setting another booby trap for someone who tries to make ipath work on a 32-bit architecture.
