[ Upstream commit bfb670b918 ]
When a fatal signal is pending or the process is freezing,
btrfs_trim_block_group() and btrfs_trim_free_extents() return -ERESTARTSYS.
Currently this is treated as a regular error: the loops continue to the
next iteration and count it as a block group or device failure.
Instead, break out of the loops immediately and return -ERESTARTSYS to
userspace without counting it as a failure. Also skip the device loop
entirely if the block group loop was interrupted.
