RDMA/hns: Remove redundant 'use_lowmem' argument from hns_roce_init_hem_table()

Browse Source 
As hns_roce_init_hem_table() is always called with use_lowmem
being '1', and table->lowmem is set according to that argument,
so remove table->lowmem too.

Also, as the table->lowmem is used to indicate a dma buffer
is allocated with GFP_HIGHUSER or GFP_KERNEL, and calling
dma_alloc_coherent() with GFP_KERNEL seems like a common
pattern.
