Quiet ptrace error ESRCH in regsets_fetch_inferior_registers
When I run process-dies-while-detaching.exp with GDBserver, I see many
warnings printed by GDBserver,
ptrace(regsets_fetch_inferior_registers) PID=26183: No such process
ptrace(regsets_fetch_inferior_registers) PID=26183: No such process
ptrace(regsets_fetch_inferior_registers) PID=26184: No such process
ptrace(regsets_fetch_inferior_registers) PID=26184: No such process
regsets_fetch_inferior_registers is called when GDBserver resumes each
lwp.

The is the case that threads are disappeared when GDB/GDBserver resumes
them. We check errno for ESRCH, and don't print error messages, like
what we are doing in regsets_store_inferior_registers.

* linux-low.c (regsets_fetch_inferior_registers): Check
errno is ESRCH or not.
