[ Upstream commit 3892b11eac5aaaeefbf717f1953288b77759d9e2 ]
Currently, there are some places to set CSR.PRMD.PWE, the first one is
in hw_breakpoint_thread_switch() to enable user space singlestep via
checking TIF_SINGLESTEP, the second one is in hw_breakpoint_control() to
enable user space watchpoint. For the latter case, it should also check
TIF_LOAD_WATCH to make the logic correct and clear.
Fixes: c8e57ab0995c ("LoongArch: Trigger user-space watchpoints correctly")
