Remove a BUG_ON for when interrupts are disabled during an MMC request. During boot, interrupts can be disabled when a request is made, causing this bug to be triggered. In reality, there's no reason this should halt the kernel, as the driver has proved reliable in spite of disabled interrupts, and additionally, there's nothing in this code that would require interrupts to be enabled. The only setup I've managed to make it trigger on is on the HTC Herald during bootup when the driver is built into the kernel (mostly because that's all I have). I believe it's related to the fact that on bootup I get many timeout errors on "CMD5" while initializing the card. Each CMD5 timeout triggers that bug (I changed it to a WARN_ON to get it to boot in) due to the fact that part of the timeout code involves sending the request again. With interrupts turned off, that BUG would be triggered.
