sysclk-lwla: Fix a regression with (at least) the LWLA1034.

This regression was introduced in f1ba6b4b2c9a8ecf90bb31efb218752aa7e49d1a.

Due to how the sysclk-lwla driver does up to 3 open/close operations in
one dev_open() API callback we cannot rely on the sr_dev_open() and
sr_dev_close() wrappers setting the sdi->status variable in this case.

Tested on LWLA1034.
