staging: iio: tsl2x7x: remove unnecessary code 

As a follow up to the work in commit a0722d05a1 ("staging: iio:
tsl2x7x: convert mutex_trylock() to mutex_lock()"), this patch removes
the unnecessary calls to tsl2x7x_get_prox() and tsl2x7x_get_lux() in
tsl2x7x_event_handler(). Previously, these functions were locked with
mutex_trylock(), but that is no longer the case. This patch also removes
a comment that is no longer relevant about returning the last sample.
