cryptodev-module: Backport a patch to fix build failure with kernel v5.8
Fix the following build failure with linux-yocto-dev
zc.c:61:17: error: 'struct mm_struct' has no member named 'mmap_sem';
did you mean 'mmap_base'?
61 | down_read(&mm->mmap_sem);
| ^~~~~~~~
| mmap_base
zc.c:77:15: error: 'struct mm_struct' has no member named 'mmap_sem';
did you mean 'mmap_base'?
77 | up_read(&mm->mmap_sem);
| ^~~~~~~~
| mmap_base
