Subject: [PATCH] atm: idt77252: Fix the size used in a 'dma_alloc_coherent()' call

This should be TSQSIZE in order to be consistent with the surrounding code
and the corresponding 'dma_free_coherent()' in 'deinit_tsq()'

This is harmless because RSQSIZE and TSQSIZE have the same value (i.e.
8192)

Fixes: 	1da177e4c3f4 ("Linux-2.6.12-rc2")
