x86, PEBS/DS: fix code flow in ds_request()
this compiler warning:
arch/x86/kernel/ds.c: In function 'ds_request':
arch/x86/kernel/ds.c:368: warning: 'context' may be used uninitialized in this function
Shows that the code flow in ds_request() is buggy - it goes into
the unlock+release-context path even when the context is not allocated
yet.
First allocate the context, then do the other checks.
Also, take care with GFP allocations under the ds_lock spinlock.
