Subject: [PATCH net] docs: networking: timestamping: improve stacked PHC sentence

The first paragraph makes no grammatical sense. I suppose a portion of
the intended sentece is missing: "[The challenge with ] stacked PHCs
(...) is that they uncover bugs".

Rephrase, and at the same time simplify the structure of the sentence a
little bit, it is not easy to follow.

Fixes: 94d9f78f4d64 ("docs: networking: timestamping: add section for stacked PHC devices")

 3.2.4 Other caveats for MAC drivers
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-Stacked PHCs, especially DSA (but not only) - since that doesn't require any
-modification to MAC drivers, so it is more difficult to ensure correctness of
-all possible code paths - is that they uncover bugs which were impossible to
-trigger before the existence of stacked PTP clocks.  One example has to do with
-this line of code, already presented earlier::
