prot_sg_cnt cannot be zero as a previous check on ret (from which
prot_sg_cnt is assigned) returns -ENOMEM if is it zero. Since
it cannot be zero we can simplify the code by removing the non
-zero check on prot_sg_cnt and redundant else statement.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
