firmware-qcom-sdm845-hdk: fix path for the SLPI firmware (#1588)

The recipe specifies FW_QCOM_DIR as a location of the device-specific
firmware, however firmware-qcom.inc uses FW_QCOM_SUBDIR. Correct the
variable name to move HDK-specific firmware (SLPI) to the correct
location.

Fixes: 1cff037 ("firmware-qcom-sdm845-hdk: package SLPI firmware
for SDM845-HDK")
