block: don't add partitions if GD_SUPPRESS_PART_SCAN is set
[ Upstream commit 748008e1da926a814cc0a054c81ca614408b1b0c ]
Commit b9684a71fca7 ("block, loop: support partitions without scanning")
adds GD_SUPPRESS_PART_SCAN for replacing part function of
GENHD_FL_NO_PART. But looks blk_add_partitions() is missed, since
loop doesn't want to add partitions if GENHD_FL_NO_PART was set.
And it causes regression on libblockdev (as called from udisks) which
operates with the LO_FLAGS_PARTSCAN.
Fixes the issue by not adding partitions if GD_SUPPRESS_PART_SCAN is
set.
