ksmbd: implement error handling for STATUS_INFO_LENGTH_MISMATCH in smb server

Browse source

Add STATUS_INFO_LENGTH_MISMATCH mapping to EMSGSIZE.
Currently, STATUS_INFO_LENGTH_MISMATCH has no mapping to any error code,
making it difficult to distinguish between invalid parameters and length
mismatch.

Map STATUS_INFO_LENGTH_MISMATCH to EMSGSIZE while keeping the EINVAL for
invalid parameters. Although the buf_len check only checks for buf_size
being less than required, there was no error code for lower buf_size.
Hence, EMSGSIZE is used.
