[dunfell PATCH] cryptodev-module: Backport a patch to fix build failure with kernel v5.11

[Nishanth Menon]

Fix the following build failure with v5.11+ kernel
cryptodev-module/1.10-r0.arago0/git/authenc.c: In function 'pad_record':
cryptodev-module/1.10-r0.arago0/git/authenc.c:317:2: warning: ISO C90 forbids variable length array 'pad' [-Wvla]
 317 |  uint8_t pad[block_size];
     |  ^~~~~~~
cryptodev-module/1.10-r0.arago0/git/ioctl.c: In function 'cryptodev_ioctl':
cryptodev-module/1.10-r0.arago0/git/ioctl.c:875:4: error: implicit declaration of function 'ksys_close'; did you mean 'ksys_chown'? [-Werror=implicit-function-declaration]
 875 |    ksys_close(fd);
     |    ^~~~~~~~~~
     |    ksys_chown


OE Core does'nt plan on fixing dunfell branch up for newer kernel, and
oe master already is on 1.12 cryptodev with the fixes already in place.

oe master is already at 1.12 release which has this fix incorporated, so
this should NOT be applied on meta-arago master.

dunfell has fixes for the previous kernel already, so we just append to
the list of fixes from oe-core.
