coresight: tmc: Remove duplicate memset

Browse source 
The tmc_etr_enable_hw() fills the buffer with 0's before enabling
the hardware. So, we don't need an explicit memset() in
tmc_enable_etr_sink_sysfs() before calling the tmc_etr_enable_hw().
This patch removes the explicit memset from tmc_enable_etr_sink_sysfs.
