Re: [U-Boot] [PATCH] env_nand: return error when no device is found

Currently, if there is an error probing the NAND chip and the env is based in NAND, the readenv() function will use a NULL function pointer and thus jump to address 0.

Here I just check for a non-zero value of blocksize as that shouldn't be zero when a valid device is found, but perhaps there is a better way for someone familiar with the NAND internals to suggest.

Applies clean to 69a2a4d9a5884a6f2d04a551308980d452b9b349 of git://git.denx.de/u-boot.git.

Tested on da850evm_config with NAND enabled, board boots fine.
