ide: abort TRIM operation for invalid range
ATA8-ACS3, 7.9 DATA SET MANAGEMENT - 06h, DMA 7.9.5 Error Outputs If the Trim bit is set to one and: a) the device detects an invalid LBA Range Entry; or b) count is greater than IDENTIFY DEVICE data word 105 (see 7.16.7.55), then the device shall return command aborted. A device may trim one or more LBA Range Entries before it returns command aborted. See table 209. This check is not in the common ide_dma_cb() as the range for TRIM is harder to reach: it is not in LBA/count registers and the buffer has to be parsed first.
