Michael J. Ruhl b53ae6bc7e IB/hfi1: set_intr_bits uses incorrect source for register modification
HFI IRQ enable bits are not being set correctly.  Send context error and
DC IRQs are not being enabled correctly.  In addition, send context error
IRQs are not being delivered.

Because of this, send context errors are not being handled correctly when
they occur.

When setting the IRQ bits, if an IRQ range is used, and the last bit is on
a register boundary (bit 63), the calculated index for the final register
modification is incorrect (index + 1 vs. index).

The incorrect index calculation causes incorrect IRQ bits to be set.  In
this case the send context error IRQ is NOT enabled.

Fix by using the 'last' value rather than the counted 'src' value to
determine the final index to use.  This satisfies all cases.
