irqs: add IRQF_SAMPLE_RANDOM to the feature-removal-schedule.txt (deprecated) list

This adds IRQF_SAMPLE_RANDOM to the feature-removal (deprecated) list
since most of the IRQF_SAMPLE_RANDOM users are technically bogus as
entropy sources in the kernel's current entropy model.

This was discussed on the lkml the past few days, which started here:

+What:   IRQF_SAMPLE_RANDOM
+Check:  IRQF_SAMPLE_RANDOM
+When:   July 2009
+
+Why:    Many of IRQF_SAMPLE_RANDOM users are technically bogus as entropy
+        sources in the kernel's current entropy model. To resolve this, every
+        input point to the kernel's entropy pool needs to better document the
+        type of entropy source it actually is. This will be replaced with
+        additional add_*_randomness functions in drivers/char/random.c
