OTA: Fix linux BlockEOF with data length zero

[woody-apple]

Problem

Fixes issue #22308 where linux currently doesn't support BlockEOF of data length zero.

Change overview

Remove this check, it is checked immediately after in SetBlock: https://github.com/project-chip/connectedhomeip/blob/master/src/platform/Linux/OTAImageProcessorImpl.cpp#L244
But at this point the block is released correctly and it does not return an error.

Testing

Did an ota which finished with a BlockEOF with data length zero and confirmed it finished.
