s390/chsc: fix packed-not-aligned warnings
Remove attribute packed where possible failing this add proper alignment information to fix warnings like the one below: drivers/s390/cio/chsc.c: In function 'chsc_siosl': drivers/s390/cio/chsc.c:1287:2: warning: alignment 1 of 'struct <anonymous>' is less than 4 [-Wpacked-not-aligned] } __attribute__ ((packed)) *siosl_area; Note: this patch should be a nop since non of these structs use auto storage but allocated pages. However there are changes to the generated code because of additional padding at the end of some of the structs due to alignment when memset(foo, 0, sizeof(*foo)) is used.
