scsi: nsp32: fix logic bug in error handling

gcc-8 points out a logic error that has existed since the start of the
git history:

drivers/scsi/nsp32.c: In function 'nsp32_selection_autoscsi':
drivers/scsi/nsp32.c:607:27: error: bitwise comparison always evaluates to false [-Werror=tautological-compare]
  if(((phase & BUSMON_BSY) == 1) || (phase & BUSMON_SEL) == 1) {
                           ^~

Presumably the author intended to check if one of two bits was set, so
that's what I'm changing the code to. This will obviously change the
behavior of the code, hopefully to do the right thing, but I have not
tested this or checked if the new "(phase & BUSMON_BSY) || (phase &
BUSMON_SEL)" condition should indeed be treated as a fatal error.
