s390/airq: remove lsi_mask from airq_struct
Remove the field `lsi_mask` from `struct airq_struct` as it is not
utilized for any adapter interrupt, other than setting it to the default
value of 0xff.
Because nobody is using this functionality, all it does is cost a little
bit of time with each delivered adapter interrupt.
