IB/qib: Convert timers to use timer_setup()

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
helper to pass the timer pointer explicitly.

IB/qib: Begin to use rdmavt for verbs

This patch begins to make use of rdmavt by registering with it and
providing access to the header files. This is just the beginning of
rdmavt support in qib.

Most functionality is still being done in the driver, set flags so that
rdmavt will let qib continue to handle mr, qp, and cq init.

IB/qib: checkpatch fixes

Elminate some simple_strto* usage.

checkpatch also noted pr_ conversations, which have been done as
recommended. The pr_fmt() define is used to shorten line length.

Other multi-line string warnings are also elmininated.

IB/qib: Ensure that LOS and DFE are being turned off

Due to timing, it is possible for the LOS and DFE to remain on. This
is due to the link progressing to LinkUP prior to the driver getting
the first Status Changed interrupt. By expanding the conditions under
which LOS is turned off and DFE timeout is being set, timing is no
longer an issue.

IB/qib: Handle transitions from ACTIVE_DEFERRED to ACTIVE better

When the link transitions from ACTIVE_DEFERRED to ACTIVE, the driver
only sees the ACTIVE state. With this change, it will check whether
the state was already ACTIVE and if so, it will not generated IB
events and will not clear symbol error counts.
