video: tegra: nvmap: Correct the data type

Browse Source 
When granule_size of type u32 and size is more than 4GB (i.e. value
having more than 32 bits), then ALIGN_GRANULE_SIZE would return
incorrect value due to ~(GRANULE_SIZE - 1),  as this would be in 32
bits. Hence change the granule size's data type to size_t, so that the
above value is not restricted to 32 bits.
