[PATCH v4 0/6] staging: rtl8723bs: convert xmit init path to standard error codes

[Hungyu Lin]

Convert the xmit initialization path to use standard kernel
return conventions (0 on success, negative errno on failure).

This replaces the use of _SUCCESS/_FAIL with proper error
codes and improves error propagation.

The changes are split into smaller patches following review
feedback from Dan Carpenter, converting one function at a time
to make the series easier to review.

v4:
- Split into a series of smaller patches as suggested by Dan Carpenter
- Convert functions step by step to improve reviewability
- Ensure each patch builds independently

v3:
- Rebase onto latest staging-next to resolve conflicts.

v2:
- Rework xmit init path to remove _SUCCESS/_FAIL usage
- Convert allocation helpers to return standard error codes
- Update caller to use direct failure checks
- Address review feedback from Ethan Tidmore
