sata_sil24: sil24_interrupt() micro-optimisation
sil24_interrupt() loads host->ports[i] into a local variable, validates it, and then loads the value again in the call to sil24_host_intr(). This patch replaces the second load by a reference to the local variable. This is safe since no side-effects have occurred since the initial load. It also improves readability since it makes it clear that the parameter to sil24_host_intr() is the same value which was just validated.
