md: Fix linear_set_limits()
commit a572593ac80e51eb69ecede7e614289fcccdbf8d upstream.
queue_limits_cancel_update() must only be called if
queue_limits_start_update() is called first. Remove the
queue_limits_cancel_update() call from linear_set_limits() because
there is no corresponding queue_limits_start_update() call.
This bug was discovered by annotating all mutex operations with clang
thread-safety attributes and by building the kernel with clang and
-Wthread-safety.
