[SQL] [MINOR] [DOC] Clarify docs for inferring DataFrame from RDD of …

…Products * Makes `SQLImplicits.rddToDataFrameHolder` scaladoc consistent with `SQLContext.createDataFrame[A <: Product](rdd: RDD[A])` since the former is essentially a wrapper for the latter * Clarifies `createDataFrame[A <: Product]` scaladoc to apply for any `RDD[Product]`, not just case classes Author: Feynman Liang <[email protected]> Closes #8406 from feynmanliang/sql-doc-fixes. (cherry picked from commit 642c43c) Signed-off-by: Reynold Xin <[email protected]>
