[RESEND PATCH v2 1/5] staging: lustre: ldlm_extent.c: replace IS_PO2 by is_power_of_2

Replaces IS_PO2 by is_power_of_2. It is more accurate to use is_power_of_2 since it returns 1 for numbers that are powers of 2 only whereas IS_PO2 returns 1 for 0 and numbers that are powers of 2. Signed-off-by: Aya Mahfouz --- v2: -changed commit message
