iio:core: Fix bug in length of event info_mask and catch unhandled bits set in masks.
The unhandled bits case was highlighted by smatch:
CHECK drivers/iio/industrialio-core.c
drivers/iio/industrialio-core.c:719 iio_device_add_info_mask_type() error: buffer overflow 'iio_chan_info_postfix' 17 <= 31
CC [M] drivers/iio/industrialio-core.o
CHECK drivers/iio/industrialio-event.c
drivers/iio/industrialio-event.c:327 iio_device_add_event() error: buffer overflow 'iio_ev_info_text' 3 <= 3
The incorrect limit for the for_each_set_bit loop was noticed whilst fixing
this other case. Note that as we only have 3 possible entries a the moment
and the value was set to 4, the bug would not have any effect currently.
It will bite fairly soon though, so best fix it now.
