Subject: [PATCH] nvmem: include linux/err.h from header

missing err.h header file can cause simillar errors like below
in some configurations.
"error: implicit declaration of function 'ERR_PTR'
[-Werror=implicit-function-declaration]"

This adds the missing include to ensure we can always include
the header.
