ice: fix AQ error code comparison in ice_set_pauseparam()

Browse Source 
Fix unreachable code: the conditionals in ice_set_pauseparam() used
the bitwise-AND operator suggesting aq_failures is a bitmap, but it
is actually an enum, making the third condition logically unreachable.

Replace the if-else ladder with a switch statement.  Also move the
aq_failures initialization to the variable declaration and remove the
redundant zeroing from ice_set_fc().
