Slark Xiao c2d55304db net: wwan: Fix MRU mismatch issue which may lead to data connection lost

commit f542cdfa3083a309e3caafbbdf41490c4935492a upstream.

In pci_generic.c there is a 'mru_default' in struct mhi_pci_dev_info.
This value shall be used for whole mhi if it's given a value for a specific product.
But in function mhi_net_rx_refill_work(), it's still using hard code value MHI_DEFAULT_MRU.
'mru_default' shall have higher priority than MHI_DEFAULT_MRU.
And after checking, this change could help fix a data connection lost issue.
