Subject: [PATCH net-next 2/3] net: ipa: fix another QMI message definition

The ipa_init_modem_driver_req_ei[] encoding array for the
INIT_MODEM_DRIVER request message has some errors in it.

First, the tlv_type associated with the hw_stats_quota_size field is
wrong; it duplicates the valiue used for the hw_stats_quota_base_addr
field (0x1f) and should use 0x20 instead.  The tlv_type value for
the hw_stats_drop_size field also uses the same duplicate value; it
should use 0x22 instead.

Second, there is no definition for the hw_stats_drop_base_addr
field.  It is an optional 32-bit enumerated type value.

Finally, the hw_stats_quota_base_addr, hw_stats_quota_size, and
hw_stats_drop_size fields are defined as enumerated types; they
should be unsigned 4-byte values.
