firewire: core: fix upper bound of possible CSR allocations
region->end is defined as an upper bound of the requested address range, exclusive --- i.e. as an address outside of the range in which the requested CSR is to be placed. Hence 0x0001,0000,0000,0000 is the biggest valid region->end, not 0x0000,ffff,ffff,fffc like the current check asserted. For simplicity, the fix drops the region->end & 3 test because there is no actual problem with these bits set in region->end. The allocated address range will be quadlet aligned and of a size of multiple quadlets due to the checks for region->start & 3 and handler->length & 3 alone.
