xfs: ensure rtx mask/shift are correct after growfs

When growfs sets an extent size, it doesn't updated the m_rtxblklog and
m_rtxblkmask values, which could lead to incorrect usage of them if they
were set before and can't be used for the new extent size.

Add a xfs_mount_sb_set_rextsize helper that updates the two fields, and
also use it when calculating the new RT geometry instead of disabling
the optimization there.
