Jiantao Shan c15b5c6fab LoongArch: Fix access error when read fault on a write-only VMA ... commit efb44ff64c95340b06331fc48634b99efc9dd77c upstream. As with most architectures, allow handling of read faults in VMAs that have VM_WRITE but without VM_READ (WRITE implies READ). Otherwise, reading before writing a write-only memory will error while reading after writing everything is fine. BTW, move the VM_EXEC judgement before VM_READ/VM_WRITE to make logic a little clearer.
