Filipe Manana 51dad05f18 btrfs: fix off-by-one chunk length calculation at contains_pending_extent() 
[ Upstream commit ae6bd7f9b4 ]

At contains_pending_extent() the value of the end offset of a chunk we
found in the device's allocation state io tree is inclusive, so when
we calculate the length we pass to the in_range() macro, we must sum
1 to the expression "physical_end - physical_offset".

In practice the wrong calculation should be harmless as chunks sizes
are never 1 byte and we should never have 1 byte ranges of unallocated
space. Nevertheless fix the wrong calculation.
