ata: libata-scsi: fix ata_dsm_trim_pages() kernel-docgrafted

make htmldocs fails with:

  Documentation/driver-api/libata:604: ./drivers/ata/libata-scsi.c:2301:
  ERROR: Unexpected indentation. [docutils]

The Return: section of ata_dsm_trim_pages() ends its first sentence with
a colon and continues with an indented bullet list. reStructuredText
requires a blank line before an indented block, so docutils chokes on
the list.

Simply adding the missing blank line does not work either: Return: is a
kernel-doc "special section", which is terminated by the first blank
line, so the bullet list would end up in the Description section,
detached from the sentence introducing it.

Spell the two bounds out as prose instead, so that the Return: section
stays self-contained. Documentation-only change.

+eBPF Userspace API
+==================
+
+eBPF is a kernel mechanism to provide a sandboxed runtime environment in the
+Linux kernel for runtime extension and instrumentation without changing kernel
+source code or loading kernel modules. eBPF programs can be attached to various
+kernel subsystems, including networking, tracing and Linux security modules
+(LSM).
+
+For internal kernel documentation on eBPF, see Documentation/bpf/index.rst.
