Remove unused legacy btree traces from IRIX era.

Talking to Dave about it, he mentioned XFS_BTREE_TRACE_CURSOR might be worth to
turn into a proper ftrace trace point, so I didn't touch _CURSOR traces in this
patchset, and a proper conversion will be sent later, unless it's not worth at
all, and I should send a V2 also removing TRACE_CURSOR.

TBH I wonder the opposite -- why not turn all of these into tracepoints?

TBH, we haven't used them in at least 15 years. What value do they
provide apart from making the traces even noisier (and potentially
more lossy) than they already are?

Cheers,

Dave.
