ntb: use 64-bit arithmetic for the MSI doorbell mask
commit fd5625fc86922f36bedee5846fefd647b7e72751 upstream.
msi_db_mask is of type 'u64', still the standard 'int' arithmetic is
performed to compute its value.
While most of the ntb_hw drivers actually don't utilize the higher 32
bits of the doorbell mask now, this may be the case for Switchtec - see
switchtec_ntb_init_db().
Found by Linux Verification Center (linuxtesting.org) with SVACE static
analysis tool.
Fixes: 2b0569b3b7e6 ("NTB: Add MSI interrupt support to ntb_transport")
