scsi: qla2xxx: Make qla_trim_buf() and __qla_adjust_buf() static

Smatch reports:

drivers/scsi/qla2xxx/qla_mid.c:1189:6: warning: symbol 'qla_trim_buf' was not declared. Should it be static?
drivers/scsi/qla2xxx/qla_mid.c:1221:6: warning: symbol '__qla_adjust_buf' was not declared. Should it be static?

These functions are only used in qla_mid.c, so they should be static.
