staging: rtl8723bs: update _rtw_pktfile_read() to return error codes

The function _rtw_pktfile_read() currently returns a uint and clamps
the requested read length if it exceeds the remaining data. This
behavior makes it impossible to propagate error codes from internal
calls like skb_copy_bits() and leads to incomplete data processing.

This patch updates the function to:
    1. Return -EINVAL if the remaining data is less than the requested length,
       ensuring callers always get the full amount of data they expect.

    2. Propagate the negative error code from skb_copy_bits().

    3. Change the return type from uint to int to support these error codes.

To avoid breaking git bisect, this patch also updates all call sites
(set_qos, update_attrib, and rtw_xmitframe_coalesce) in the same commit.
By doing so, the error-producing function and its error-handling callers
remain in sync, preventing runtime failures at this commit point.
