ieee80211_aes_gmac() uses the mic argument directly in sg_set_buf() and that does not allow use of stack memory (e.g., BUG_ON() is hit in sg_set_buf() with CONFIG_DEBUG_SG). BIP GMAC TX side is fine for this since it can use the skb data buffer, but the RX side was using a stack variable for deriving the local MIC value to compare against the received one. Fix this by allocating heap memory for the mic buffer. This was found with hwsim test case ap_cipher_bip_gmac_128 hitting that BUG_ON() and kernel panic.

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.
