Simplify the error handling in pkcs1pad_create() by taking advantage of crypto_grab_akcipher() now handling an ERR_PTR() name and by taking advantage of crypto_drop_akcipher() now accepting (as a no-op) a spawn that hasn't been grabbed yet. While we're at it, also simplify the way the hash_name optional argument is handled. We only need to check whether it's present in one place, and we can just assign directly to ctx->digest_info.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
