wait_for_completion_timeout returns an unsigned long not int. declare a
suitably type timeout and fix up assignment and check.

Found during code review.
Given that CQSPI_READ_TIMEOUT_MS is < INT_MAX the type conversion is safe
here but it is cleaner to use proper types.
Patch was compile tested with: socfpga_defconfig (implies
CONFIG_SPI_CADENCE_QUADSPI=y)
Patch is against 4.18-rc5 (localversion-next is next-20180720)
