fix(onedrive): direct upload small file error

[WoLeo-Z]

OpenListTeam/OpenList#1668

Description / 描述

• Simply remove the file.size > chunkSize check in the Frontend.

Motivation and Context / 背景

Relates to #249

When uploading files (size <= ChunkSize), server side uses upBig logic (for chunked upload) to request for the upload url, therefore the PUT request needs a header Content-Range.

But in frontend uploadSingle don't specify this header. Causing Upload failed with status 400.

{"error":{"code":"invalidRequest","message":"The Content-Range header is missing or malformed."}}

How Has This Been Tested? / 测试

0 < smallFileLimit (e.g. 4mb) < default ChunkSize (e.g. 5mb)

So there are 3 situations:

• 3.5mb: Client receives ChunkSize = 0 and uses uploadSingle (1 PUT request)
• 4.5mb: Client receives ChunkSize > 0 and uses uploadChunk but ChunkCount = 1 (1 PUT request)
• 5.5mb: Client receives ChunkSize > 0 and uses uploadChunk but ChunkCount > 1 (multiple PUT requests)

fallocate -l 3.5M 3.5M.bin
fallocate -l 4.5M 4.5M.bin
fallocate -l 5.5M 5.5M.bin

Removing the file.size > chunkSize check may causing other direct upload functions broken. Review before merging.

(IMO if the file don't need chunked upload, chunkSize should be set 0.)
