misc: alcor_pci: fix inverted branch condition

Browse source

commit 281e468446 upstream.

This patch fixes a trivial mistake that I made in the previous attempt
in fixing the null bridge issue. The branch condition is inverted and we
should call alcor_pci_find_cap_offset() only if bridge is not null.
