perf cs-etm: Fix definition of macro TO_CS_QUEUE_NR
Macro TO_CS_QUEUE_NR definition has a typo, which uses 'trace_id_chan'
as its parameter, this doesn't match with its definition body which uses
'trace_chan_id'. So renames the parameter to 'trace_chan_id'.
It's luck to have a local variable 'trace_chan_id' in the function
cs_etm__setup_queue(), even we wrongly define the macro TO_CS_QUEUE_NR,
the local variable 'trace_chan_id' is used rather than the macro's
parameter 'trace_id_chan'; so the compiler doesn't complain for this
before.
After renaming the parameter, it leads to a compiling error due
cs_etm__setup_queue() has no variable 'trace_id_chan'. This patch uses
the variable 'trace_chan_id' for the macro so that fixes the compiling
error.
