[PATCH 6.6 03/24] xfs: consider minlen sized extents in xfs_rtallocate_extent_block

commit 944df75958807d56f2db9fdc769eb15dd9f0366a upstream.

[backport: resolve merge conflict due to missing xfs_rtxlen_t type]

minlen is the lower bound on the extent length that the caller can
accept, and maxlen is at this point the maximal available length.
This means a minlen extent is perfectly fine to use, so do it. This
matches the equivalent logic in xfs_rtallocate_extent_exact that also
accepts a minlen sized extent.
