btrfs: don't warn if discard range is not aligned to sector
commit a208b3f132b48e1f94f620024e66fea635925877 upstream.
There's a warning in btrfs_issue_discard() when the range is not aligned
to 512 bytes, originally added in 4d89d377bbb0 ("btrfs:
btrfs_issue_discard ensure offset/length are aligned to sector
boundaries"). We can't do sub-sector writes anyway so the adjustment is
the only thing that we can do and the warning is unnecessary.
