misc: habanalabs: pci: Scrub documentation for non-present function argument

'dma_mask' is not passed directly into hl_pci_set_dma_mask() as
an argument.  Instead, it is pulled from struct hl_device *hdev.

Fixed the following W=1 warning:

 drivers/misc/habanalabs/pci.c:328: warning: Excess function parameter 'dma_mask' description in 'hl_pci_set_dma_mask
