Fix a few issues with the generic "save" shell command, and fs_write()
function.
1) fstypes[].write wasn't filled in for some file-systems, and isn't
checked when used, which could cause crashes/... if executing save
on e.g. fat/ext filesystems.
2) fs_write() requires the length argument to be non-zero, since it needs
to know exactly how many bytes to write. Adjust the comments and code
according to this.
3) fs_write() wasn't prototyped in <fs.h> like other generic functions;
other code should be able to call this directly rather than invoking
the "save" shell command.
