Return X86_XSTATE_SSE_MASK instead of 0 in i386fbsd_core_read_xcr0

i386fbsd_core_read_xcr0 reads the value of xcr0 from the corefile.  If
it fails, returns 0.  This makes its caller {i386,amd64}_target_description
has to handle this special value.  IMO, i386fbsd_core_read_xcr0 should
return the default xcr0 in case of error.
