Input: cs40l50 - fix wrong usage of INIT_WORK()

In cs40l50_add(), the work_data is a local variable and the work_data.work
should initialize with INIT_WORK_ONSTACK() instead of INIT_WORK().
Small error in cs40l50_erase() also fixed in this commit.

Fixes: c38fe1bb5d21 ("Input: cs40l50 - Add support for the CS40L50 haptic driver")
