idpf: add missing cpu_to_le32 in idpf_tx_splitq_build_flow_desc

Browse Source 
idpf_tx_splitq_build_flow_desc performs a 32-bit store to &cmd_dtype
to set the 8-bit cmd_dtype and zero the adjacent 3-byte timestamp
field in a single operation.

Descriptors are in little endian. Add missing cpu_to_le32 and cast to
__le32 to ensure the fields are written correctly also on big endian
platforms.
