[PATCH mm 1/1] filemap: Remove redundant folio_test_large check in filemap_free_folio

['Guanjun' <guanjun@linux.alibaba.com>]

From: Guanjun <guanjun@linux.alibaba.com>

The folio_test_large check in filemap_free_folio is unnecessary because
folio_nr_pages, which is called internally, already performs this check.
Removing the redundant condition simplifies the code and avoids double
validation.

This change improves code readability and reduces unnecessary operations
in the folio freeing path.
