s390/ptrace: remove leftover comment

Browse Source 
The code which validates floating point control register contents was
reworked with commit 702644249d ("s390/fpu: get rid of test_fp_ctl()").

There is still a comment which refers to the old implementation - remove it
in order to avoid confusion.
