IMPALA-14859: Fix crashes in parquet-column-chunk-reader.cc
If running out of memory when trying to uncompress dictionary page
buffer during parquet read, there was a crash, because there was an
assumption that dict_page_pool_ failed to allocate it, but
dict_page_pool_ is not initialized in this case, so there is a nullptr
dereference.
The error was fixed by only referencing dict_page_pool_ in the path
where it is valid, and reverting the other path to reference parent's
dictionary_pool_, which always exists.
The error was introduced in IMPALA-14794
with commit 49f0ab1d09541f960cee12e9a5e6aa38ec21565a
