scsi: qla2xxx: Initialize 'n' before using it
The following code:
qla82xx_rom_fast_read(ha, 0, &n)
only initializes 'n' if it succeeds. Since 'n' may be reported in a debug
message even if no ROM reads succeeded, initialize 'n' to zero.
This patch fixes the following sparse warning:
qla_nx.c:1218: qla82xx_pinit_from_rom() error: uninitialized symbol 'n'.
