Under heavy memory loads and fragmentation, such a request can fail. Previous versions of the driver have dropped the packet and reused the old buffer; however, the new version introduced a bug in that it released the old buffer before trying to allocate a new one. The previous method is implemented here.

Realtek is working on a change to the RX buffer allocation, but that is likely to be too invasive for a fix to -rc or stable. In the meantime, this will help.23/23? Where are patches 1-22? I don't see them in patchwork: https://patchwork.kernel.org/project/linux-wireless/list/
Sorry. I forgot to edit the subject line. To get git to format that one patch, I had to generate a total of 23. There is only 1 of 1 that will be submitted.
