Christopher Haster 4db96d4d44 Changed unwritable superblock to ENOSPC for consistency
While ECORRUPT is not a wrong error code, it doesn't match other
instances of hitting a corrupt block during write. During writes, if
blocks are detected as corrupt their data is evicted and moved to a new
clean block. This means that at the end of a disk's lifetime, exhaustion
errors will be reported as ENOSPC when littlefs can't find any new block
to store the data.

This has the benefit of matching behaviour when a new file is written
and no more blocks can be found, due to either a small disk or corrupted
blocks on disk. To littlefs it's like the disk shrinks in size over
time.
