ARM: 6330/1: perf: reword comments relating to perf_event_do_pending
This is purely a cosmetic change to the ARM perf backend because the current
comments about the relationship between NMIs, interrupt context and
perf_event_do_pending are misleading.
This patch updates the comments so that they reflect what the code
actually does (which is in line with other architectures).
