Commit be36f9e7517e ("efi: READ_ONCE rng seed size before munmap") added a READ_ONCE() and also changed the call to add_bootloader_randomness() to use the local size variable. Neither of these changes was actually needed and this was not backported to the 4.14 stable branch.
Commit 161a438d730d ("efi: random: reduce seed size to 32 bytes") reverted the addition of READ_ONCE() and added a limit to the value of size. This depends on the earlier commit, because size can now differ from seed->size, but it was wrongly backported to the 4.14 stable branch by itself.
Apply the missing change to the add_bootloader_randomness() parameter (except that here we are still using add_device_randomness()).
